In grade school or middle school, your science teacher might present you with a project to keep ice from melting. Keeping ice from melting is also a common science fair project undertaken by children in these grade levels. The trick to keeping ice from melting is to insulate it, keeping the surrounding temperature low. Even the smallest amount of heat will expedite the rate at which ice will melt. You cannot keep ice from melting forever without a freezer, but you can postpone it for extended periods with the right method.

Cut an opening out of a large styrofoam block. The opening should be equal to the width and length of the ice you want to keep from melting. Use a knife to carve the opening into the centre of the block. Save the cutaway material for later. Place the styrofoam block, and reserved piece, in a freezer.
Wrap the ice in a sheet of cling film. This holds any melted water against the ice cube, helping maintain a low temperature.
Place the wrapped ice into the hole in the styrofoam block. Fill the top of the hole with the reserved styrofoam pieces.
Place the styrofoam block in the centre of a large cardboard box. Line the box with housing insulation.
Keep the box out of the sun. Avoid contact with excessive heat.
Tips and warnings
- Use the largest styrofoam block and cardboard box possible to best insulate the ice.
- Do not handle knives or housing insulation without a responsible adult's assistance or supervision.
