I'm gonna try to demonstrate something called regelation.

Which is where you provide a pressure onto ice

and that turns it into water but after that pressure is removed it freezes again

So, in order to demonstrate this I've taken apart the high E string from my guitar.

I chose the E string because it's thinner than a G string and that's important.

And I've weighted it with these two bottles of water.

When I apply the string across the ice we should see the wire start to cut through the ice

where we'll see if it works because we are outside in Sydney and it's warmer than 0°C obviously.

All right, it's past 3 A.M. but the experiment has been a success

I passed this wire through this giant block of ice

You can actually see the point where the wire went through, here.

So, we pretty clearly demonstrated regelation.

The idea that you can compress the ice, turn it into water and then

when that pressure is gone it solidifies again as ice.
