This is never going to work.

It would take days to freeze this much ice cream.

0:00:030:00:06

All set for our world-record attempt, Ms Hucklebuck?

0:00:060:00:10

Well, almost. There is one slight concern with the...

0:00:100:00:14

Excellent. Soon, my masterpiece will be complete -

0:00:140:00:18

the world's biggest ice cream cone.

0:00:180:00:21

HE CACKLES

0:00:210:00:22

This won't end well.

BELL RINGS

0:00:260:00:27

We're live in five, four, three...

0:00:270:00:30

ANNOUNCER: This is...

0:00:300:00:33

With...

0:00:330:00:35

..the floor manager.

0:00:400:00:41

Stand by!

0:00:440:00:46

Come on, everybody!

0:00:460:00:47

-BOTH:

-It's time for...

0:00:510:00:52

Today, we're asking, can ice cubes sink in water?

0:00:550:00:58

At a microscopic level, invisible to our eyes,

0:00:580:01:01

water consists of two hydrogen atoms and one oxygen atom

0:01:010:01:05

bonded together to form a molecule.

0:01:050:01:08

Water can exist in three different states -

0:01:080:01:10

liquid, gas and solid.

0:01:100:01:13

As a liquid, the molecules are close together,

0:01:130:01:15

but free to flow around each other.

0:01:150:01:18

As a gas, the molecules are far apart and can move in

0:01:180:01:21

all different directions.

0:01:210:01:23

But when water hits its freezing point at zero degrees Celsius,

0:01:230:01:26

the molecules take on a solid form known as ice.

0:01:260:01:30

Speaking of ice,

0:01:300:01:31

I wonder how my super-cone is doing.

0:01:310:01:33

HE HUMS A TUNE

0:01:330:01:34

-SHE SIGHS

-See you after the break.

0:01:340:01:36

And we're clear.

0:01:370:01:39

This is it, McCork,

0:01:390:01:41

the moment we've all been waiting for.

0:01:410:01:44

Let the pour begin.

0:01:440:01:46

But it's not frozen.

0:01:460:01:48

He said, "Let the pour begin."

0:01:480:01:51

OK. You asked for it.

Uh-oh!

0:01:540:01:55

ALARM BLARES

0:01:550:01:56

No, this is all wrong!

0:01:580:02:00

Stop the machine! Stop the machine!

0:02:000:02:03

I can't. It's broken!

0:02:030:02:06

I told you this was a bad idea.

0:02:060:02:08

Run for your life!

0:02:080:02:09

BELL RINGS

0:02:090:02:10

Positions, everyone.

0:02:100:02:12

If you can find them.

0:02:120:02:14

So tell us, Dr Knowles, can ice cubes sink in water?

0:02:190:02:23

First, let me ask YOU a question.

0:02:230:02:25

If we took two identical jars and filled one with popcorn

0:02:250:02:29

and the other with marbles, which one would be lighter?

0:02:290:02:32

The popcorn one, obviously.

0:02:320:02:34

Correct. Even though both jars are equal in volume -

0:02:340:02:37

that is the popcorn and marbles take up the same amount of space -

0:02:370:02:41

the first jar weighs less because

0:02:410:02:43

the popcorn is less dense than the marbles.

0:02:430:02:45

Less dense?

0:02:450:02:47

Well, what has all that got to do with ice?

0:02:470:02:49

The molecules in ice are arranged

0:02:490:02:51

in a rigid framework that allow the water molecules

0:02:510:02:53

to be more spread out, a bit like the popcorn in the first jar.

0:02:530:02:56

Whereas the molecules in a liquid are more tightly packed together,

0:02:560:03:00

more like the marbles.

0:03:000:03:01

And if an object is less dense than the fluid it's in, it will float.

0:03:010:03:05

If it's more dense, it will sink.

0:03:050:03:07

So ice always floats in water because it's less dense?

0:03:070:03:12

Exactly. Now you've got it.

0:03:120:03:15

Ha! Maybe I'm not that dense after all, Doctor.

0:03:170:03:19

Oh! I think we better get out of here, Professor.

0:03:190:03:22

See you next time, folks. I hope!

0:03:220:03:25

-COLIN:

-And we're clear.

0:03:260:03:27

So, then, Mr Artiste, what have you got to say for yourself?

0:03:270:03:31

Can't talk, slurping.

0:03:310:03:33

HE SLURPS

0:03:330:03:34

News just in, everyone,

0:03:340:03:37

looks like we've got the world record...

0:03:370:03:40

What?

0:03:400:03:41

..for world's biggest milkshake.

0:03:410:03:45

Heh! Another one in the bag. HE SLURPS

0:03:450:03:48

-Oh, come on. This is ridiculous.

-Mm.

0:03:480:03:50

Even by our standards.

0:03:500:03:52

Colin, sometimes you just have to trust in the artistic process.

0:03:520:03:56

Just suck it up.

0:03:560:03:57
