I'm going to try to demonstrate
something called regulation, 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 uh 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 uh the wire start to cut
through the ice and perform the the
regulation of the ice. Well, we'll see
if it works because we are outside in
Sydney and it's warmer than 0 degrees
obviously.

All right, it's past 3:00 a.m., but the
experiment has been a success. I passed
this wire through this giant block of
ice, and it's still a solid block. You
can actually see the point where the
wire went through here. So, we pretty
clearly demonstrated regulation, the
idea that you can compress the ice, turn
it into water, and then when that
pressure is gone, it solidifies again as
ice.
Pretty cool stuff.
