Um, but you skate on it, skate on it, but you know that it feels pretty slippery, doesn't it?

It does feel slippery, but you would feel a different sleepiness to May because I skate for a living because the ratio ratio of friction versus air on water, frozen water.

So I'm here on an ice rink in Sydney and I've been asking people, Why is ice slippery now?

A lot of them kind of have the right idea.

They say there's a layer of water on top of the ice, but they don't know why.

They think it's just because the sun's out or because it's warm in Sydney and the ice melts.

So I wanted to know why Isis slippery where the freezing meets the less than freezing state, it becomes a liquid.

So it's a liquid on top of the frozen state that makes it separate.

I mean, like, down here, it's not so wet, Right?

Water, for instance, on here will lubricate, and you'll have better sliding surface than you will with the dry ice like live vacations on the way, because the sun has hated off the ice because it smelt the particles.

Even if there was no sun depends on the actual hate.

The real reason is when you step on the ice, you compress it a bit, and that decreases its melting point.

And so we get a thin layer of water that you can glide along.

If you would just slide on your belly across the water bit, you obviously get very wet.

But you'd slide a lot further than you would on the drive section.

Have you tried that in Brisbane during the pack down of the event, I took one of our inflatable tubes.

I didn't think I was gonna get very far because the ice was melting.

I managed to slide 60 meters from front 10 yard run up 60 meters the whole way across the room.

That's pretty impressive but I was very happy with the way I was gonna get that far.

But it doesn't actually have to be warm out.

And you still get this lame, slippery effect because it's based on pressure, not the temperature of the outside air.
