I made this volcano for my youngest daughter's 7th birthday. She wanted to have a swim party, but it was too cold. She settled for a luau. I put a small shot glass in the center of the wondermold cake and had a piece of dry ice in it. It was supposed to have lava flowing out of the top, but the eggwhites which were tinted red, didn't seem to want to boil out over the top. She enjoyed it anyways!
