OK, Gastronuts, let's find out what our challenge is this week.

0:00:020:00:05

Da-da-da!

0:00:050:00:07

Can we make a plastic bag from mashed potato?

0:00:090:00:13

LAUGHTER

0:00:130:00:15

BURPS

0:00:340:00:35

The Gastronuts doing weird stuff with food today are,

0:00:350:00:38

If I can use food in a new way, I'll use

0:00:490:00:52

pizza for a steering wheel in a car.

0:00:520:00:54

When I'm not putting salt and pepper on my food

0:00:540:00:57

I like putting it in my friend's drink as a prank.

0:00:570:01:00

Coming up on today's show,

0:01:000:01:02

I get up close to some really fast food.

0:01:020:01:05

That is so cool!

0:01:070:01:08

The Gastronuts and I have a small difference of opinion.

0:01:080:01:13

I do think it's the best food on the planet.

0:01:130:01:16

Yuk!

0:01:160:01:18

And we find out what's been stuck up my drainpipe.

0:01:180:01:21

Whay-hey!

0:01:210:01:23

That was the best one! Look, it went miles!

0:01:230:01:26

-What is food for?

-Food fights.

-If you're naughty, I guess so.

0:01:280:01:31

-Eating.

-For eating. It gives us fuel, doesn't it?

0:01:310:01:34

It gives us the energy to last the day.

0:01:340:01:36

But what else can food make that isn't part of us?

0:01:360:01:39

-Cheese string glasses.

-In a world of fantasy, you could!

0:01:390:01:43

-Pasta earrings.

-You can turn spices into make-up or perfume.

0:01:430:01:47

-There's cream made out of coconut butter?

-Mustard for face paints?

0:01:470:01:51

That would hurt! Anything else that we can use food for?

0:01:510:01:54

You can stick together cow intestines and that to make a belt.

0:01:540:01:59

It's mad, but you could. The big question is,

0:01:590:02:01

can we make plastic bags out of mashed potato?

0:02:010:02:05

-I think so.

-No?

-Not sure. I think so.

-Let's give it a go.

0:02:050:02:09

-Let's give it a go. Come on, then, guys, follow me.

-Yeah.

0:02:090:02:12

Let's start off by taking some potatoes.

0:02:150:02:18

OK, they need to go into the blender. Go on, get in there.

0:02:180:02:21

We just need a little bit of water to make it all nice and soppy.

0:02:210:02:24

Woo-hoo! And give it a good whizz.

0:02:240:02:26

OK, Ben, I think we're done there.

0:02:300:02:32

What we've got in here is all the starch from the potatoes

0:02:320:02:35

which will give us a really good solid substance,

0:02:350:02:38

but we need to take the water out of it.

0:02:380:02:40

-Whoa!

-It looks like porridge now.

0:02:400:02:43

It's like porridge, sick, potato milkshake.

0:02:430:02:46

OK, now we need to get all of the water so we're

0:02:460:02:49

just left with all the starch.

0:02:490:02:51

Busting out a little bit,

0:02:510:02:52

I think we've started to make little holes in the muslin.

0:02:520:02:56

Woo-hoo! OK, let's have a look at what we've got here. Whoa!

0:02:560:02:59

-That looks like cheese.

-What does it smell like?

0:02:590:03:02

-Oww!

-It smells really strange. It smells almost like sort of

0:03:020:03:07

-petrol or something.

-It smells like raw potatoes.

0:03:070:03:10

-It's quite potent, isn't it?

-Yeah.

0:03:100:03:12

It's almost like a biofuel already.

0:03:120:03:14

To turn our mash into plastic we're adding vinegar,

0:03:140:03:17

a sugary liquid called glycerin and some water.

0:03:170:03:20

We then let it all simmer together.

0:03:200:03:23

So why do you think we're bothering

0:03:230:03:25

to make a plastic bag out of potatoes?

0:03:250:03:27

Maybe because it's something different and it's

0:03:270:03:30

-a little bit more, what's the word? Environmental.

-Yeah.

0:03:300:03:33

-It's good to experiment.

-You're right.

0:03:330:03:35

To make things out of oil you need to keep taking oil out of the ground

0:03:350:03:39

and oil is beginning to run out, so we need to start finding other

0:03:390:03:42

ways to make the things we need.

0:03:420:03:44

Do you know how long it takes a normal plastic bag to degrade,

0:03:440:03:47

-to turn into mush?

-About a year?

-Two years?

-Two to five months?

0:03:470:03:51

The truth is nobody really knows because none of the plastic

0:03:510:03:54

has degraded yet, so we don't know.

0:03:540:03:56

-I think that should be nearly ready. Isn't that weird?

-It's all goo.

0:03:560:04:00

The potato has definitely turned into something else, hasn't it?

0:04:000:04:04

It's become a very different substance.

0:04:040:04:06

There's some magic of science that's gone on there somewhere.

0:04:060:04:10

Let's grab that baking tray over there.

0:04:100:04:12

-OK.

-Oh! Oh, that is cool.

-The mash mix is poured on

0:04:120:04:18

to a baking tray and popped in the oven for a couple of hours.

0:04:180:04:21

Bags made from starch are becoming available

0:04:210:04:24

in the shops. They look just like normal bags,

0:04:240:04:26

but what will ours look like?

0:04:260:04:28

-So, does that look like a carrier bag?

-No.

0:04:280:04:30

No. What does it feel like?

0:04:300:04:31

It feels kind of like a plastic bag.

0:04:310:04:34

It is sort of plasticky, isn't it? Here we go, then.

0:04:340:04:37

We're going to try and transform this pile of goo into a plastic bag.

0:04:370:04:43

We're going to staple our bag together

0:04:430:04:45

and see if that does the job.

0:04:450:04:48

I think we need a bit of branding on this, don't we?

0:04:480:04:51

Very good!

0:04:510:04:52

Let's take those small potatoes.

0:04:520:04:55

Let's see how many we can get in there.

0:04:550:04:57

And another one. And another one!

0:04:580:05:00

Arub, I'd like you to carry my carrier bag.

0:05:000:05:03

Let's see how many potatoes we can get in before she goes.

0:05:030:05:08

Oh-ho!

0:05:080:05:09

I know it sounds quite disgusting, but if you added some string

0:05:090:05:13

and you went to the countryside,

0:05:130:05:15

it might look a tiny bit like a cow-skin bag.

0:05:150:05:17

Like a cow-skin bag! It could do.

0:05:170:05:20

I wouldn't really want to be caught with that in the supermarket.

0:05:200:05:23

Let's try one more thing.

0:05:230:05:25

OK, let's pop this down here.

0:05:250:05:27

Most carrier bags have a handle, don't they?

0:05:270:05:29

There we go.

0:05:290:05:31

I would say that is a plastic bag!

0:05:310:05:34

OK, our bag doesn't look great, but it does prove

0:05:340:05:37

that you can make plastic that doesn't need oil

0:05:370:05:40

and won't take years to break down.

0:05:400:05:42

Amazing! It's as though food has got secrets waiting to be teased out.

0:05:420:05:46

You can turn it into so many different things,

0:05:460:05:48

but I wonder how far we can go with taking food

0:05:480:05:51

and changing it into something different?

0:05:510:05:53

I was really surprised that a potato plastic bag

0:05:530:05:58

can carry more than five potatoes.

0:05:580:05:59

In recent years, people have learnt how food can be usefully turned

0:06:020:06:06

into new substances.

0:06:060:06:08

In the past, the kitchen was where the earliest science took place,

0:06:080:06:11

sometimes with explosive results.

0:06:110:06:13

So Gastronuts, who likes doing science at school?

0:06:130:06:16

-Me.

-Yeah! Cooking is very much like chemistry.

0:06:160:06:19

Mixing ingredients together,

0:06:190:06:21

applying heat and changing it into something else.

0:06:210:06:23

So I just want to show you something that uses food

0:06:230:06:27

in a little chemical experiment.

0:06:270:06:29

Here we have some bicarbonate of soda, and here we have some vinegar.

0:06:290:06:32

What I'd like you to do, Connor,

0:06:320:06:34

is tip the bicarbonate of soda into the vinegar.

0:06:340:06:38

I wouldn't hold on to, actually, if I were you.

0:06:380:06:40

Give it a good old tip and see what happens.

0:06:400:06:43

-Oh, it's fizzing!

-Yes.

0:06:430:06:45

Now, what's happening there is that the acid in the vinegar

0:06:450:06:48

is reacting with the bicarbonate of soda,

0:06:480:06:50

creating carbon dioxide, making it fizz.

0:06:500:06:52

When you put bicarbonate of soda into cakes,

0:06:520:06:55

it helps things to rise, it puts air inside them,

0:06:550:06:58

it makes them light and fluffy.

0:06:580:06:59

I wondered if we could take this reaction

0:06:590:07:01

and build it up on a bigger scale and make something more exciting.

0:07:010:07:05

-Would you like to try that?

-Yeah!

-OK, follow me.

0:07:050:07:07

Now then, I want you all to wait here for a second,

0:07:070:07:11

because I need to go and find a friend I'd like you to meet.

0:07:110:07:14

Hold on there.

0:07:140:07:16

Many people believe that experimenting

0:07:160:07:18

in the kitchen was where modern science began.

0:07:180:07:21

We're going to see how we can take something familiar,

0:07:210:07:25

like making a cake rise, and turn it into something really cool.

0:07:250:07:28

Ladies and gentlemen, I'd like to introduce you to my friend BBB.

0:07:280:07:32

This is Barry The Bicarbonate-Of-Soda Bazooka.

0:07:320:07:34

Bazooka?!

0:07:340:07:35

Now, what does a bazooka do?

0:07:350:07:37

You put a rocket in the end and it goes...ppwwrrr!

0:07:370:07:41

We've taken a length of pipe you'd use in your guttering

0:07:410:07:44

and attached it to a pivot with some wheels.

0:07:440:07:46

That's the bazooka, now to make our missiles.

0:07:460:07:49

We're going to use bicarbonate of soda and vinegar and try and use

0:07:490:07:52

all the gas that's given off by the reaction between those

0:07:520:07:56

to build up pressure, and when that pressure releases, hopefully,

0:07:560:07:59

we'll make something that will blow off.

0:07:590:08:01

We start with a bottle. Connor, grab one of those bottles.

0:08:010:08:05

Any bottle. Choose a bottle, any bottle.

0:08:050:08:07

OK, now we need to fill it with about two inches of vinegar.

0:08:070:08:12

Stop.

0:08:120:08:13

Brilliant. Now for the other side of it.

0:08:130:08:16

This is a piece of pipe with a bung stopping it at the end

0:08:160:08:19

and we're going to put our bicarbonate of soda into there.

0:08:190:08:22

Imogen, you grab that.

0:08:220:08:24

So, there...

0:08:240:08:25

OK, that will do perfectly.

0:08:250:08:27

Now, this is the tricky bit.

0:08:270:08:29

What we're doing is we're keeping the bicarbonate of soda

0:08:290:08:32

and the vinegar separate until the very last minute,

0:08:320:08:35

and when we put this stopper in to bung it up,

0:08:350:08:39

hopefully we'll be able to create lots of pressure,

0:08:390:08:42

and when that pressure eventually pushes the bung out of the bottom,

0:08:420:08:46

all of the pressure in the bottle will be released.

0:08:460:08:49

The bung keeps it nice and tight, so there's nothing in there.

0:08:490:08:52

And then, we need to pop it into Barry The Bazooka.

0:08:520:08:56

Mixing vinegar and baking powder in large amounts can be dangerous,

0:08:560:08:59

so do not try this at home, unless you're a member of the armed forces

0:08:590:09:04

or you're making a cake the size of a house!

0:09:040:09:07

What we're going to do is we're going to put the ammunition

0:09:070:09:11

into Barry and then we're going to lift him up,

0:09:110:09:14

so that the bicarbonate of soda mixes with the vinegar.

0:09:140:09:18

Our aim is to try and hit the bucket over there.

0:09:180:09:22

-So Connor, are we facing the right way?

-No, wait, I'll just do the aim.

0:09:220:09:26

Fire!

0:09:260:09:28

Yeah, it's over here. A little bit to the...more...

0:09:280:09:32

Let's go.

0:09:320:09:33

OK, here's one for Ben.

0:09:350:09:36

The bottle with the bicarb and vinegar is placed inside.

0:09:360:09:40

A strap over the end stops the bottle falling out

0:09:400:09:42

when we tip up our bazooka.

0:09:420:09:44

All the way to the top.

0:09:440:09:45

Once we've tipped it up, the bicarb and vinegar fizz together.

0:09:450:09:49

We release the strap, take aim

0:09:490:09:51

and wait for our bottle to blow out of the pipe.

0:09:510:09:53

-How long does it take?

-Well, I don't really know.

0:09:530:09:57

In fact... Oh, there we go!

0:09:570:09:59

Well, it works. It didn't get quite far enough, though.

0:10:000:10:03

Maybe I need to shake it more.

0:10:030:10:05

Maybe we need more vinegar. Maybe I should push the bung in tighter.

0:10:050:10:09

OK, next one, then.

0:10:090:10:12

Give it a shake. Lovely. And back down.

0:10:120:10:14

Shall we give it a count to see how long it takes?

0:10:140:10:17

One. Two.

0:10:170:10:19

Three. Four.

0:10:190:10:21

Five. Six. Seven.

0:10:210:10:23

Eight. Nine.

0:10:230:10:26

A-ho! Woo-hoo!

0:10:260:10:28

That went miles!

0:10:300:10:31

Farther than yours, mate.

0:10:310:10:33

I wonder if we can stick it in

0:10:330:10:35

a bit tighter and get it even further?

0:10:350:10:37

Go on then, go for it. A good old shake.

0:10:370:10:39

OK.

0:10:390:10:40

I can't hear anything happening.

0:10:430:10:45

Well, maybe we should just all sit about and have a bit of a rest.

0:10:460:10:50

Let's do a dance.

0:10:500:10:51

-No!

-A dance?

-A dance-off!

-What are we going to dance?

0:10:510:10:54

# Gastronuts, eee, eee, eee, eee!

0:10:540:10:57

# Gastronuts, eee, eee, eee, eee! #

0:10:570:11:00

Can we not just show them G or something?

0:11:000:11:03

I do hope this works. They're starting to frighten me!

0:11:030:11:06

This isn't happening. Let's give it another shake.

0:11:060:11:10

OK, let's go.

0:11:100:11:11

-OK, down!

-It's going to bang!

-Take cover!

0:11:140:11:17

Whoa ho!

0:11:180:11:19

That was the best one! Look, it went miles!

0:11:210:11:23

-Take aim.

-OK.

0:11:230:11:26

-Happy with that?

-Yeah.

0:11:260:11:28

Give her a shake.

0:11:280:11:30

And back up again.

0:11:300:11:32

-Take aim.

-We sit and we wait.

0:11:320:11:34

Whoa! Oh, you hit the bucket as well!

0:11:360:11:39

Brilliant! Top man. Give me five.

0:11:390:11:41

Imogen's eliminated!

0:11:410:11:43

-Guys, what do you think about this?

-That was just wicked.

0:11:430:11:47

-I liked that.

-That was the best bit, I think.

0:11:470:11:49

-What do you think of Barry?

-Can I keep him?

0:11:490:11:53

We've proved you can actually power a bazooka

0:11:530:11:56

using the same process we use to make a cake rise.

0:11:560:11:58

And that's the great thing about food, it doesn't just feed us,

0:11:580:12:02

it can lead us into thinking about the world in a completely new way.

0:12:020:12:06

BURPS

0:12:060:12:08

We all spend huge amounts of our time eating,

0:12:080:12:11

thinking about our food and playing with our food,

0:12:110:12:14

but when you start getting scientists

0:12:140:12:16

experimenting with their food, strange things happen.

0:12:160:12:20

Some brainboxes at Warwick University have come up with a use

0:12:200:12:23

for old fruit and veg that is completely car-azy.

0:12:230:12:27

Steve, how are you doing?

0:12:270:12:29

Hello, Stefan.

0:12:290:12:30

So you play with your food on a professional basis?

0:12:300:12:33

We do experiments looking at how we can use different foods for

0:12:330:12:36

different things and we are looking at making things from carrots

0:12:360:12:40

and from soya beans and from chocolate.

0:12:400:12:42

Sounds fantastic. Anything useful you can show us?

0:12:420:12:45

I've got a project over here that looks like fast food.

0:12:450:12:48

-This is James, our racing driver.

-Hello, James. Nice to meet you.

0:12:590:13:03

It's a very cool racing car, but what's she got to do with food?

0:13:030:13:06

There are a number of technologies on this car

0:13:060:13:09

which are based on foodstuffs.

0:13:090:13:11

So for example, the steering wheel is actually made from

0:13:110:13:15

carrots and other root vegetables.

0:13:150:13:17

That's absolutely solid.

0:13:170:13:18

Does it make a particularly good steering wheel?

0:13:180:13:21

Absolutely. I mean, that particular material is used

0:13:210:13:24

in fishing rods and other things

0:13:240:13:26

and we've made it into a steering wheel and it's great.

0:13:260:13:29

It's lightweight, strong, perfect!

0:13:290:13:31

What else? Nothing here looks like it's made out of food.

0:13:310:13:34

OK, well the seat itself is made from a foam material.

0:13:340:13:37

That would normally be made from crude oil,

0:13:370:13:40

but that one is actually made from soya beans.

0:13:400:13:43

Does it keep your bum warm?

0:13:430:13:44

No, it's just meant to be squidgy and give you support on your hips

0:13:440:13:48

so you don't get shaken around on corners.

0:13:480:13:50

So what else here is made out of foods and plants and vegetables?

0:13:500:13:53

If we look at the bib underneath the car here,

0:13:530:13:56

that's made out of a flax material.

0:13:560:13:58

Flax is a plant that is grown in the field.

0:13:580:14:00

You usually make things like sheets out of that,

0:14:000:14:03

pillowcases and that sort of thing.

0:14:030:14:04

We've made wing mirrors out of potato starch.

0:14:040:14:07

If you take a potato and you're turning it into your crisps,

0:14:070:14:10

you slice your potato into lots of thin pieces

0:14:100:14:12

and you get left with a starchy residue on the blades,

0:14:120:14:15

and that starch you can then turn into packaging material

0:14:150:14:18

and that's what we've made our wing mirrors out of.

0:14:180:14:21

Do you drive around going, "I'm driving something made out food!"

0:14:210:14:24

It's amazing. Sometimes we wonder whether

0:14:240:14:27

they're going to hold together, but we've done our work properly,

0:14:270:14:30

and the foodstuff and natural fibres are all good quality

0:14:300:14:33

and strong enough for the car.

0:14:330:14:35

Time to see how a car made out of food sounds and goes.

0:14:350:14:39

So how fast would the car go?

0:14:440:14:46

Well, currently it goes about 135 miles an hour,

0:14:460:14:49

but with a bit more engineering, we think we can get up to about 140.

0:14:490:14:52

Wow!

0:14:550:14:56

That's a car made of vegetables!

0:14:560:14:59

Yeah, but the best thing is what we actually run it on.

0:14:590:15:01

This car runs on biofuel made from the fat squeezed out from beef,

0:15:010:15:06

salmon and, best of all, chocolate.

0:15:060:15:09

-That is the most extraordinary thing, running a car on fish!

-Yes.

0:15:090:15:12

That is so cool! Does it smell of salmon?

0:15:120:15:14

-That one does a bit.

-It smells of fish oil, yeah.

0:15:140:15:17

Anything that produces a fatty substance, we can make fuel from.

0:15:170:15:20

We can make fuel for about 15p a litre,

0:15:200:15:23

compared to about £1 a litre at the petrol pump.

0:15:230:15:27

So not only is it using up a waste product,

0:15:270:15:30

but it's really cheap as well.

0:15:300:15:32

Yeah, it makes sense, it really does.

0:15:320:15:34

This car is cool.

0:15:340:15:36

Made from root veggies, soya beans and plant fibres,

0:15:360:15:40

it really is fast food!

0:15:400:15:44

What's extraordinary about this car

0:15:440:15:46

is that it's not just mucking about with food.

0:15:460:15:48

These are really high-tech, high-performance uses of food.

0:15:480:15:52

It's absolutely brilliant.

0:15:520:15:53

How do you make corn starch boogie without touching it?

0:16:010:16:06

What we need is corn starch and then we're going to add

0:16:060:16:09

a little water to it.

0:16:090:16:11

Something amazing happens, as it forms

0:16:110:16:14

a very, very strange mess.

0:16:140:16:16

When you try and stir it, it won't let you. It stiffens and it cracks.

0:16:160:16:21

What we're going to do now is we're going to add a little bit

0:16:210:16:25

of food colouring, just so that we can see it

0:16:250:16:27

a little better.

0:16:270:16:29

So our corn starch is ready

0:16:290:16:31

and I'm going to put it

0:16:310:16:32

into my special dancing-corn-starch speaker.

0:16:320:16:36

Plop!

0:16:360:16:37

BUZZING

0:16:410:16:44

It looks like it's alive!

0:16:450:16:47

So what's going on here?

0:16:490:16:51

Is it a solid or is it a liquid?

0:16:510:16:53

Well, actually, it's a bit of both.

0:16:530:16:56

You have the liquid, water, which is surrounding

0:16:560:16:58

particles of the corn starch.

0:16:580:17:00

In our speaker, where the speaker is

0:17:000:17:02

bouncing up and down, very, very slowly, we can get those particles

0:17:020:17:07

to jump past each other and build those very strange arms and legs.

0:17:070:17:12

So corn starch and water are a little bit like sand and water,

0:17:120:17:17

a bit like when you go to the beach and you run on wet sand,

0:17:170:17:21

and it feels quite firm,

0:17:210:17:23

and then when you stop, it goes all soft and you sink into it.

0:17:230:17:27

We're trying to find out if we can do more with food than just eat it.

0:17:310:17:35

So far, we've turned a sack of spuds into a plastic bag.

0:17:350:17:39

I wouldn't want to be caught with that in the supermarket!

0:17:390:17:42

And seen some food on the go.

0:17:420:17:44

It's a car made of vegetables!

0:17:440:17:46

Next up, the Gastronuts sample the fat of the hand.

0:17:460:17:49

It looks like wee.

0:17:490:17:51

And find out what's the ultimate in flexible food.

0:17:510:17:53

That's steaming, isn't it?

0:17:530:17:55

Whoa!

0:17:550:17:56

-Yes!

-Wow! That one went miles!

0:17:560:17:59

OK, we've got a massive treat for you today.

0:18:010:18:03

I have to admit,

0:18:030:18:04

not everyone else feels the same about this as I do, but I think

0:18:040:18:07

it's the best food on the planet.

0:18:070:18:09

Have a little try of that one there.

0:18:090:18:11

-Don't you like it?

-It tastes like slime.

0:18:160:18:18

This is called lardo. It's pork fat. Who knows what that is?

0:18:180:18:22

-Cheese.

-It looks like cheese.

0:18:220:18:23

It looks like cheese, but it's not. It's lard.

0:18:230:18:26

We use lard these days for baking or to fry with,

0:18:260:18:29

but in the past, it was used for all sorts of things,

0:18:290:18:32

some of which are very surprising.

0:18:320:18:34

So what else could we use it for?

0:18:340:18:36

-Face cream?

-Well, let's take that crazy idea and let's see

0:18:360:18:39

if we can make something that we could wash ourselves with, yeah?

0:18:390:18:43

-OK.

-First of all we need to turn the lard into liquid.

0:18:430:18:45

OK, now it's time to do the dangerous bit.

0:18:450:18:49

Glasses on, everybody.

0:18:490:18:50

We are going to make a solution of caustic soda.

0:18:520:18:56

It's very, very alkaline,

0:18:560:18:57

so it dissolves anything that's organic. Now, Arub,

0:18:570:19:01

be very careful. If you pour that bowl

0:19:010:19:03

of caustic soda into the water very gently,

0:19:030:19:06

so it doesn't splash. That's it, the whole lot.

0:19:060:19:09

Brilliant.

0:19:090:19:10

Now give it a gentle stir.

0:19:100:19:12

-Imogen, I want you to touch the side of the bowl.

-Oh! Ah!

0:19:120:19:15

It's really hot. It feels like boiling water, almost.

0:19:150:19:19

That's a chemical reaction going on

0:19:190:19:21

between the water and the caustic soda and it makes it very hot.

0:19:210:19:24

-How is your fat doing over there?

-It's all melted.

0:19:240:19:27

All melted, brilliant. Now, what we need to do is

0:19:270:19:30

pour that hot fat into a bowl.

0:19:300:19:32

Oh, that's nice.

0:19:320:19:34

That is melted lard.

0:19:340:19:37

It looks like oil.

0:19:370:19:38

It looks like wee, doesn't it? Let's be honest, here, it looks like wee.

0:19:380:19:42

Well, the wee you do first thing in the morning!

0:19:420:19:44

These ones here are cool.

0:19:440:19:45

We're going to put them into the blender.

0:19:450:19:47

Arub, if you can pour in the caustic soda.

0:19:470:19:50

And give it a whizz.

0:19:520:19:53

It looks like milk, but in a really weird way.

0:19:550:19:58

OK, stop it there for a sec. OK, that's looking nice and thick now.

0:19:580:20:02

Oh, yeah!

0:20:020:20:03

OK, now what we need to do is put a little bit of flavouring into it.

0:20:030:20:07

We've got some rosemary. Woo-hoo! That'll do. Turn it off again.

0:20:070:20:11

Brilliant! Now, if you can pour it into this, this is our mould.

0:20:110:20:16

Would you put that on your skin?

0:20:160:20:17

-No.

-No.

0:20:170:20:18

The mixture needs to cool overnight in the fridge,

0:20:180:20:21

but don't mistake it for hummus if you get the munchies!

0:20:210:20:24

The idea is that the runny pig fat

0:20:240:20:26

and dangerous chemicals should combine to make soap.

0:20:260:20:29

I might let the Gastronuts try it out first!

0:20:290:20:32

Chuck it out there.

0:20:320:20:33

So that was caustic soda in there. Now it's something very different.

0:20:340:20:38

Everyone got clean hands? Clean hands are no good.

0:20:380:20:41

Let's make them dirty.

0:20:410:20:43

OK, Ben, if you can pass me a piece of coal.

0:20:430:20:45

Pass us another piece of coal.

0:20:450:20:48

And another piece.

0:20:480:20:49

In the olden days, when people used to pass round coal for fun,

0:20:490:20:52

most soap was made from lard.

0:20:520:20:54

Let's see if out attempt works.

0:20:540:20:57

-OK, everyone nice and mucky?

-Yeah.

0:20:580:21:02

OK. Lard and caustic soda, soap.

0:21:020:21:05

Can everyone get in there?

0:21:050:21:07

Does it feel like normal soap? Can anyone get some suds out?

0:21:070:21:11

Has anyone managed to make any lather? Any bubbles?

0:21:110:21:14

-Yeah.

-OK, I want to see super-clean hands.

0:21:140:21:17

My hands are actually almost clean.

0:21:170:21:18

It's like super soap! It's even soapier than normal soap.

0:21:180:21:22

Let's have a show of hands.

0:21:220:21:24

Whoa-ho! Are we clean?

0:21:240:21:26

-Yeah.

-We're clean! Brilliant. This shouldn't work, but it does.

0:21:260:21:30

Something that you can eat and cook with

0:21:300:21:32

can actually be transformed into soap,

0:21:320:21:35

and you can wash your little pinkies with some fat from a little piggy.

0:21:350:21:39

-It's a bit disgusting.

-Yeah.

0:21:390:21:40

But at least it cleaned our hands.

0:21:400:21:42

It's pig fat, and you don't put pig fat on your hands.

0:21:420:21:46

It's disgusting and mucky, but we've become clean, haven't we?

0:21:460:21:49

Let's see if there's anything else we can transform our food into.

0:21:490:21:53

BURPS

0:21:550:21:56

-Do you know what this is?

-Plant.

0:21:580:22:01

It's a plant, brilliant! But what sort of plant is it?

0:22:010:22:04

-Bamboo!

-It's bamboo, spot on, well done.

0:22:040:22:06

Well, bamboo is an extraordinary, extraordinary plant.

0:22:060:22:09

It's a fantastic food, but it can be used to make

0:22:090:22:13

a huge variety of different things,

0:22:130:22:14

and I want to show you some of them. Follow me.

0:22:140:22:17

-What do you think that everything here is made out of?

-Wood.

0:22:190:22:22

-Bamboo.

-Bamboo. It's all bamboo,

0:22:220:22:24

apart from a couple of bits of steel holding this up.

0:22:240:22:27

So we've got a bamboo bowl here, we've got a bamboo steamer,

0:22:270:22:31

a bamboo spit and bamboo plates.

0:22:310:22:33

We've got all sorts of bamboo things.

0:22:330:22:35

Now, the idea here is that we're going to put a fire underneath this

0:22:350:22:38

and try and steam some food in here.

0:22:380:22:40

-What do you think we should steam in our bamboo steamer?

-Bamboo.

0:22:400:22:44

Come over here and I'll show you some bamboo we can eat.

0:22:440:22:47

-Now, this is bamboo shoots.

-Oh, cool.

-It's quite nice, actually.

0:22:470:22:50

Bamboo shoots are really important for Chinese food.

0:22:500:22:53

-Who likes eating Chinese takeaway?

-Me!

0:22:530:22:56

Well, there'll be loads of bamboo shoots in there

0:22:560:22:59

and these are how they come.

0:22:590:23:00

They're really tender and they've got this sourness.

0:23:000:23:03

Really delicious food.

0:23:030:23:05

So we're going to take some of these

0:23:050:23:06

and then we're going to cook and eat them on plates made of...

0:23:060:23:10

-Bamboo.

-Bamboo. And chopsticks made of?

0:23:100:23:12

-Bamboo.

-Bamboo!

0:23:120:23:13

So we've got some so water in the bottom there,

0:23:150:23:18

we've got a bamboo steamer here,

0:23:180:23:20

all we really need to do is heat up the water enough

0:23:200:23:23

to cook those bamboo shoots.

0:23:230:23:25

Pop the lid on.

0:23:250:23:26

Time to light our fire made of wolves' tongues and swans' feet.

0:23:260:23:30

Oh, all right, it's also made out of bamboo.

0:23:300:23:33

Well, let's see if we're managing to cook our bamboo with bamboo.

0:23:330:23:37

-Oh!

-Whoa!

0:23:380:23:40

That's steaming, isn't it?

0:23:400:23:42

How cool is that? We're adding our bamboo to a tasty stir-fry.

0:23:420:23:46

We know it can be turned into almost anything, but how does it taste?

0:23:460:23:50

-That's really nice.

-I wonder if we can take the idea of using

0:23:500:23:54

bamboo for different uses and make it into something really explosive.

0:23:540:23:59

-Explosive? Sound like my kind of thing!

-Follow me!

0:23:590:24:03

-Oh...

-Oh...

0:24:030:24:04

"Oh"? That's not the reaction!

0:24:040:24:06

You're supposed to go, "YEAH!"

0:24:060:24:08

Bamboo has been used in all sorts of ways for centuries,

0:24:080:24:11

but it's also a modern environmentally-friendly material

0:24:110:24:14

that can be used to make fabric for clothes, bike frames

0:24:140:24:18

and even laptops,

0:24:180:24:21

but there's one traditional use that's still the coolest.

0:24:210:24:24

-Do you remember Barry The Bazooka?

-Yes.

-OK.

0:24:240:24:29

This is Barry's cousin.

0:24:290:24:31

Meet Colin The Cannon!

0:24:320:24:36

Made out of bamboo.

0:24:360:24:38

If it was made by the Chinese, would it be used in the Imperial Army?

0:24:380:24:42

Exactly that kind of thing.

0:24:420:24:44

Bamboo cannons were invented by the Chinese and used

0:24:440:24:48

as flame-throwers or to fire missiles.

0:24:480:24:50

With the help of explosives expert Graham, we'll be seeing

0:24:500:24:53

if we can make some food go bam-boom!

0:24:530:24:56

-So what have we got here?

-Oranges.

0:24:560:24:58

-Oranges.

-Apples, bread.

0:24:580:25:00

-Potatoes, tomatoes.

-Which one do you reckon will be best?

0:25:000:25:03

I'd say Brussels sprouts, because they're the smallest.

0:25:030:25:06

First up to the front line,

0:25:060:25:08

it's Imogen doing the best thing I've ever seen done

0:25:080:25:11

with Brussels sprouts - blowing them up!

0:25:110:25:13

Give them to me.

0:25:130:25:14

-Ready, guys?

-Yeah.

-Three, two, one,

0:25:160:25:20

go!

0:25:200:25:21

That was pretty good!

0:25:240:25:26

Quite a good scattering here. Where's the furthest one?

0:25:260:25:29

OK, I think that's the furthest one there.

0:25:290:25:32

Next up, it's Connor, with some bagel bombs.

0:25:320:25:35

How far do you reckon these are going to go? Further?

0:25:350:25:38

-They might go further.

-Yeah, are you feeling confident?

-Yeah.

0:25:380:25:42

-OK.

-Three, two, one,

0:25:420:25:45

go!

0:25:450:25:46

Woo-hoo-hoo!

0:25:460:25:48

I think you managed to toast them at same time as fire them.

0:25:480:25:51

It's a toasted bagel!

0:25:570:25:59

OK, that did pretty well. That was further than the Brussels sprout.

0:25:590:26:02

Arub is seeing if she can pip Connor with her orange.

0:26:020:26:06

Three, two, one,

0:26:060:26:08

fire!

0:26:080:26:09

It's flopped out the end, didn't it?

0:26:120:26:14

I'd say that got about ten yards.

0:26:140:26:18

And finally, Ben's trying out the world's biggest spud gun.

0:26:190:26:23

Three, two, one,

0:26:230:26:26

fire!

0:26:260:26:28

-Woo-hoo!

-Yes!

0:26:280:26:30

Wow! That one went miles!

0:26:300:26:33

Where did it go, where did it go?

0:26:330:26:35

Here it is.

Look at that, that's brilliant!

0:26:400:26:42

It's been baked in transit.

0:26:420:26:44

Fantastic!

0:26:440:26:46

So the next time you're holding off an invading Mongol army,

0:26:460:26:50

make sure you load up your bamboo cannon with some spuds!

0:26:500:26:54

Roasting the bamboo on the spit was probably

0:26:540:26:58

one of the best things in my life,

0:26:580:27:00

and I hope for more things to come up like that again.

0:27:000:27:03

The worst part was eating the pig fat, because it tasted slimy

0:27:050:27:08

and it slithered down my throat.

0:27:080:27:10

Now that I've been on Gastronuts, I don't just think about eating food,

0:27:120:27:16

I think about blasting them as well!

0:27:160:27:18

It's just kind of a bit unbelievable

0:27:200:27:22

that we made a plastic bag out of potato.

0:27:220:27:25

That was so cool, but also quite bizarre.

0:27:260:27:29

The idea that this is a bamboo cannon firing vegetables,

0:27:290:27:32

and yet it's made out of food that we eat.

0:27:320:27:34

When you think about it, there are so many things in our normal lives

0:27:340:27:38

that are made out of food and it just takes following up

0:27:380:27:41

these stories to find out all these things that blow your mind!
