What’s it about?

Water is a remarkable substance and no living being on earth can survive without it. Water in its solid form or ‘ice’ can be especially interesting. Ice is formed when liquid water cools down to ‘0’ degrees ˚C, its ‘freezing point. Let’s see what happens when concentrated ‘pressure’ is being applied to ice in the following science experiment:

Topics covered

Freezing point, Ice, Pressure

What will I need?

  • WINE BOTTLE
  • WINE CORK
  • STRING
  • 2x SPOONS
  • BLOCK OF ICE

How does it work?

Unfortunately, this section is only available in the e-book version of the project.

This science experiment works because the ‘pressure’ of the string applied to the block of ice, causes the ice to melt just below it. Pressure creates ‘heat’ causing water to form under the string and it slides down through the ice with the help of the spoons or weights on either side of the string, pulling it down. The ice freezes again just above the string as the string slides down.
