Beakman's World: Pie and Crust
00:14:49 - 00:20:27
Beakman uses a box sitting on a table designed to be the layers of the earth. He gets under the box and uses a red oven mit to push up through the box to show how magma pushes out of the earth's crust to create a volcano. He also uses a pie to demonstrate the same thing (heats too much and then the filling will come rupturing out of the crust).
