This video introduces the process of regelation.  This is when ice melts as pressure is applied to it and then re-freezes when the pressure is removed. An experiment is conducted using two lengths of wire attached to two 1.5kg masses. One wire is made from copper and the other is fishing wire.  Students are asked...

This video demonstrates how the pressure exerted by the atmosphere (10,000kg on an average person) can implode a large drum when the air inside the drum is removed (Heat water to vaporise and remove all air. Condense the vapour by cooling the drum).
