0:00:56 > 0:00:59Hello. I'm doing an important experiment -
0:00:59 > 0:01:02how long does it take to eat a sticky bun?
0:01:02 > 0:01:06The result is, it was very quick. I'm almost finished! Ha-ha!
0:01:06 > 0:01:07ALARM BEEPS
0:01:07 > 0:01:12I hear a beep, I see a flash. I wonder what they're going to ask!
0:01:15 > 0:01:17ALL: Hi, Nina!
0:01:17 > 0:01:19Hi, guys!
0:01:19 > 0:01:21We've got a question for you.
0:01:21 > 0:01:26- Why does jam make our hands sticky? - That's a brilliant question!
0:01:26 > 0:01:28Why does jam make our hands sticky?
0:01:28 > 0:01:32I've just eaten a bun that made my hands sticky too.
0:01:32 > 0:01:36Come to the lab, we'll do some experiments to investigate.
0:01:36 > 0:01:39ALL: See you soon, Nina. Bye!
0:01:39 > 0:01:40Bye!
0:01:40 > 0:01:43I'll need some help to answer this one.
0:01:43 > 0:01:44I know just who to ask.
0:01:44 > 0:01:47OK, Neurons, time to get to work.
0:02:03 > 0:02:05ALL: Neurons at the ready, Nina.
0:02:05 > 0:02:10OK. Today's question is, why does jam make our hands sticky?
0:02:10 > 0:02:14Which Neuron will be most useful to help find the answer?
0:02:14 > 0:02:16ALL: Me! Me! Me! Oh, me!
0:02:16 > 0:02:19Will it be fabulous Felix?
0:02:19 > 0:02:22I can help so very much if you need the sense of touch.
0:02:22 > 0:02:24Will it be beautiful Belle?
0:02:24 > 0:02:29I send messages to brain from ear. If there's a sound, I'll help you hear.
0:02:29 > 0:02:31Will it be lovely Luke?
0:02:31 > 0:02:33For looking and seeing, day or night,
0:02:33 > 0:02:36I'll help you with your sense of sight.
0:02:36 > 0:02:38Will it be awesome Ollie?
0:02:38 > 0:02:41If it's pongy or whiffy but you can't tell,
0:02:41 > 0:02:45- my messages help your sense of smell. - Or will it be baby Bud?
0:02:45 > 0:02:49Sour, salty, bitter or sweet, I'm your taste buddy whenever you eat!
0:02:53 > 0:02:55It's Felix!
0:02:55 > 0:02:57CHEERING
0:02:57 > 0:03:01ALL: Go, Felix! Go, Felix! Go, Felix! Go, Felix!
0:03:01 > 0:03:03Go, Felix! Go, Felix!
0:03:03 > 0:03:08Marvellous. A little touch can mean so much, Nina.
0:03:08 > 0:03:13Today's question is, why does jam make our hands sticky?
0:03:13 > 0:03:15Being sticky is something we can feel,
0:03:15 > 0:03:18so Felix our touch Neuron will help.
0:03:18 > 0:03:22I need to get the lab ready before the experimenters arrive.
0:03:24 > 0:03:26Nathan likes cartoons.
0:03:26 > 0:03:27Patricia loves music.
0:03:27 > 0:03:29Ben likes trampolines.
0:03:29 > 0:03:33They all want to find out why jam makes their hands sticky,
0:03:33 > 0:03:38so today, for one day only, they become the experimenters!
0:03:39 > 0:03:42- ALL: Hi, Nina.- Hi, guys!
0:03:42 > 0:03:44Welcome to my lab. Come in.
0:03:44 > 0:03:45Come in!
0:03:45 > 0:03:49Now, you asked, why does jam make our hands sticky?
0:03:49 > 0:03:53Which is a brilliant question, but why do you want to know?
0:03:53 > 0:03:57When I have toast and jam in the morning, my hands get sticky.
0:03:57 > 0:04:02Mine too! You have to wash them really well to get all the jam off.
0:04:02 > 0:04:06For our first experiment, we're going to use our senses.
0:04:06 > 0:04:09ALL: Whoop-whoo! A senses experiment!
0:04:09 > 0:04:11We're ready, Nina.
0:04:11 > 0:04:15- Remember you said you put jam on your toast?- Yes.
0:04:15 > 0:04:18For this experiment, we'll forget all about the toast
0:04:18 > 0:04:23and put the jam straight onto our hands! Ho-ho!
0:04:23 > 0:04:24So hands out, please.
0:04:24 > 0:04:26Hee-hee!
0:04:28 > 0:04:29Ha-ha-ha!
0:04:30 > 0:04:32Ooh!
0:04:32 > 0:04:38- Mmm! Strawberry! My favourite! - When's tasting time, Nina?
0:04:38 > 0:04:41Sorry, Bud! We're not tasting the jam,
0:04:41 > 0:04:43we're feeling it.
0:04:43 > 0:04:46Ah! I'm the Neuron for that job.
0:04:46 > 0:04:49- What does it feel like? - Sticky.- Sticky.
0:04:49 > 0:04:51Yeah! Oh-ho-ho-ho!
0:04:51 > 0:04:54Nina's fingers are almost stuck together.
0:04:54 > 0:04:59So they are! The jam is sticking my fingers together,
0:04:59 > 0:05:03a bit like glue. What other foods are sticky?
0:05:03 > 0:05:08- Toffee.- Lollies.- Honey.- They're all pretty sticky, aren't they?
0:05:08 > 0:05:12So we've found out that when something is sticky,
0:05:12 > 0:05:15it makes things stick or join together a little.
0:05:15 > 0:05:19I think we need to wash our hands and get all the sticky jam off
0:05:19 > 0:05:23because I have another jammy experiment to show you.
0:05:23 > 0:05:27For this experiment, we're going to have a food race!
0:05:27 > 0:05:31A food race?! To see how much food we can taste, Nina?
0:05:31 > 0:05:34No, we're not tasting anything, Bud.
0:05:34 > 0:05:35Aw!
0:05:35 > 0:05:39Here we have four dishes, and in this one we have some syrup,
0:05:39 > 0:05:41some olive oil,
0:05:41 > 0:05:43some ketchup
0:05:43 > 0:05:47and jam, but not too much because it's not good to waste food.
0:05:47 > 0:05:51We'll see which one reaches the bottom first.
0:05:51 > 0:05:54- Who do you think will win?- Syrup. - Syrup, OK.
0:05:54 > 0:05:57- Oil.- The oil. What do you think, Ben?- Jam.
0:05:57 > 0:06:00Oh! Well, let's see.
0:06:00 > 0:06:01OK, ready?
0:06:01 > 0:06:03On your marks,
0:06:03 > 0:06:04go!
0:06:04 > 0:06:06Come on, Ketchup!
0:06:06 > 0:06:09The olive oil's running away with it! Ha-ha!
0:06:09 > 0:06:13The syrup's picking up pace. The ketchup needs to catch up.
0:06:13 > 0:06:16Do you get it? Ketchup, catch up?
0:06:16 > 0:06:19Oh, never mind.
0:06:19 > 0:06:23We have a winner! The olive oil reached the bottom first.
0:06:23 > 0:06:26The oil is much runnier than the others,
0:06:26 > 0:06:29so it ran down the board really quickly.
0:06:29 > 0:06:32If we touch a tiny bit of oil... Have a feel.
0:06:32 > 0:06:34It's not really sticky, is it?
0:06:34 > 0:06:37I'd say that was more oily than sticky.
0:06:37 > 0:06:41So the thick ketchup is the slowest in the race,
0:06:41 > 0:06:45- but where's the jam? - It's not reached the bottom yet.
0:06:45 > 0:06:50So the jam is not a fast runner, because it's quite thick and sticky.
0:06:50 > 0:06:52So the jam's stickiness
0:06:52 > 0:06:55slowed it down because it kept sticking to the board.
0:06:55 > 0:06:58I think we need to go to a very special place
0:06:58 > 0:07:02where there's lots of lovely jars. Let's go!
0:07:02 > 0:07:03- ALL: Yes!- Woo-hoo!
0:07:09 > 0:07:12Off we go, for another adventure.
0:07:12 > 0:07:16Nina said it was somewhere with lots of jars.
0:07:16 > 0:07:20Oh, I know! The supermarket! There's lots of jars there.
0:07:20 > 0:07:23I have a feeling we're here, Neurons.
0:07:23 > 0:07:27This is it, experimenters. Any ideas what's inside?
0:07:27 > 0:07:29ALL: No.
0:07:29 > 0:07:31Well, let's go in. I have a feeling
0:07:31 > 0:07:36it's going to be jam-packed with things for us to see! Let's go.
0:07:46 > 0:07:49Here we are, everyone, at a jam factory!
0:07:49 > 0:07:52We're going to see jam being made. Ha-ha!
0:07:52 > 0:07:56Wooo... What a lovely fruity smell.
0:07:58 > 0:08:01So all the fruit is put into these big pots,
0:08:01 > 0:08:05and boiled until it breaks down into a gooey liquid.
0:08:08 > 0:08:11And then they put in syrupy liquid sugar,
0:08:11 > 0:08:15and boil it some more to make it thicker.
0:08:15 > 0:08:17This is the syrupy sugar here.
0:08:17 > 0:08:21It's a bit like the syrup from our food race.
0:08:21 > 0:08:24Woo-hoo-hoo-hoo! So let's see what happens next.
0:08:42 > 0:08:46We now have our very own jar of jam!
0:08:46 > 0:08:49- Shall we taste it?- ALL: Yeah.
0:08:49 > 0:08:51OK! Here we go...
0:08:51 > 0:08:53About time too, Nina.
0:08:54 > 0:08:56Ooh-hoo...
0:08:56 > 0:08:58Mmm...
0:09:01 > 0:09:03Ha-ha! Look at their messy faces.
0:09:03 > 0:09:08- They're covered in jam.- And Nina's got sticky fingers. Again.
0:09:08 > 0:09:13Mmmmm... But it tastes sweet!
0:09:13 > 0:09:16You're right, Bud. It does taste sweet.
0:09:16 > 0:09:17Really sweet.
0:09:17 > 0:09:20Fruit has some sugar in it naturally,
0:09:20 > 0:09:24and liquid sugar was added to the bubbling pots too.
0:09:24 > 0:09:26So sugar makes the jam taste sweet.
0:09:26 > 0:09:30Oh - but that doesn't tell us WHY it's sticky, does it?
0:09:30 > 0:09:32ALL: No.
0:09:32 > 0:09:35No. So I think we need to do one final experiment.
0:09:37 > 0:09:41So your question was, why does jam make our hands sticky?
0:09:41 > 0:09:44We've learnt that when something is sticky,
0:09:44 > 0:09:48it makes things stick or join together - like glue.
0:09:48 > 0:09:50And when we went to the jam factory,
0:09:50 > 0:09:54we discovered that jam is made from fruits and syrupy sugar.
0:09:54 > 0:09:58But we still don't know why jam is so sticky.
0:09:58 > 0:10:02- So let's get experimenting! - ALL: Yeah!
0:10:02 > 0:10:04OK, we're going to test this water
0:10:04 > 0:10:06to see how sticky it is.
0:10:06 > 0:10:08The water needs to be quite hot,
0:10:08 > 0:10:11but I've checked, and it's not burny-hot.
0:10:11 > 0:10:13So let's dip our hands in...
0:10:17 > 0:10:18So is that sticky?
0:10:18 > 0:10:20No.
0:10:20 > 0:10:25No? It's not sticky at all, is it? So let's add a little bit of sugar.
0:10:25 > 0:10:29OK, Patricia - you want to turn your tap?
0:10:29 > 0:10:30That's it!
0:10:31 > 0:10:34And now do you want to take your mixing stick,
0:10:34 > 0:10:36and give it a good stir?
0:10:37 > 0:10:39That's great, Patricia. Thank you.
0:10:39 > 0:10:42Now, let's rub a little bit on our hands.
0:10:45 > 0:10:47That's it.
0:10:47 > 0:10:50No. That's still not sticky.
0:10:50 > 0:10:54Let's add a bit more sugar. Ben, your turn - turn the tap.
0:11:03 > 0:11:05And what do they feel like now?
0:11:05 > 0:11:07It feels stickier.
0:11:07 > 0:11:12Yeah? Oh, it does. My hands are starting to join together a bit.
0:11:13 > 0:11:14Nathan - go for it.
0:11:16 > 0:11:18Oh, it's going to be VERY sticky now.
0:11:22 > 0:11:25- Oh, what does it feel like now? - Very sticky.
0:11:25 > 0:11:27Very sticky, yeah!
0:11:27 > 0:11:30It's even stickier than lolly bits.
0:11:30 > 0:11:33Oh, really, really sticky!
0:11:33 > 0:11:35My fingers are sticking together.
0:11:35 > 0:11:38I think we need to wipe them with a tissue.
0:11:39 > 0:11:41Oh...!
0:11:41 > 0:11:43Sticking instead.
0:11:43 > 0:11:45Oh! Our hands are so sticky
0:11:45 > 0:11:48that the paper tissue's sticking to them.
0:11:48 > 0:11:50What does this experiment tell us?
0:11:50 > 0:11:52The sugar made the water sticky.
0:11:52 > 0:11:56That's right. The more sugar that we added to the water,
0:11:56 > 0:11:58the stickier it got.
0:11:58 > 0:12:01And there's only one way to get this much stickiness off -
0:12:01 > 0:12:05some soap and water. So we better wash our hands!
0:12:08 > 0:12:10Oh... That's better.
0:12:10 > 0:12:12Now, your question was,
0:12:12 > 0:12:17why does jam make our hands sticky? And I think we've answered it.
0:12:17 > 0:12:21We learnt that jam is made from fruit, and lots of sweet sugar.
0:12:21 > 0:12:23Our final experiment proved
0:12:23 > 0:12:27that it's the sugar in jam that makes it sticky.
0:12:27 > 0:12:31- So I hope that's answered your question.- ALL: Thanks, Nina. Bye!
0:12:31 > 0:12:32Bye!

0:13:30 > 0:13:34It's been a marvellous day. And a very busy one.
0:13:34 > 0:13:37I've been feeling sticky things all day long.
0:13:37 > 0:13:41Ah, it's been such a great day, man.
0:13:41 > 0:13:45Seeing all that running in the food race - that was pretty fun!
0:13:45 > 0:13:47I really enjoyed myself today.
0:13:47 > 0:13:51The smell of the jam being made in the factory...
0:13:51 > 0:13:52Mmmm! Delicious.
0:13:52 > 0:13:55Oh, I've had a brilliant day.
0:13:55 > 0:14:00Hearing everyone laughing and giggling when they got really sticky
0:14:00 > 0:14:02was ace!
0:14:02 > 0:14:06Our day's been bursting with sensational experiments.
0:14:06 > 0:14:07See you soon. Bye!
