Volcano in a Tea Cup Science Project for Kids. Put some wax in the bottom of a fireproof glass container. Add some sand. Fill it up with cold water. Now carefully heat the bottom. Then the pressure becomes too much and at the weakest point, where the sand has bubbles, the hot wax shoots out in a lovely volcanic explosion.
