Salt decreases the melting point of the ice, meaning it'll mount faster.

What's another way to decrease the melting point of ice?

The answer is, you apply pressure to it tonight.

I want to do an experiment on regulation.

Regulation means you apply pressure to ice, and so it turns into water.

But when that pressure is removed, it turns back into ice.

I have two pairs of 1.5 kilogram weights.

This pair is joined by a bit of fishing line, and my other pair is joined by some copper wire.

They're both the same thickness.

Now.

I'm going to put the wire and the fishing line over this block of ice and tryto pull it through the ice.

And I want you to make a prediction which one will pass through the ice.

First will be the copper wire or the fishing line.

Or will they both passed through at the same rate?

Make your prediction.

Now you got about five seconds left.

Quick, pick one.

That's too late.
