most people know that you can melt ice
just by putting salt on it salt
decreases the melting point of the ice
meaning it'll melt 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 kilograms 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 try to
pull it through the ice and I want you
to make a prediction which one will pass
through the ice first will it be the
copper wire or the fishing line or will
they both pass through at the same rate
make your prediction now you got about
five seconds left quick pick one that's
too late
