Steve Spangler Science: Volcano in a Cup (Erupting Wax)

Create a violent, bubbling storm of wax within the confines of a cup.

When you hear about a volcano erupting, what do you think is going on? If you’re like us, you think of red hot chunks of rock being hurled thousands of feet in the air, flows of liquid magma, and plumes of smoke. That’s not always the case. Some volcanoes erupt underwater and their smoking hot by-products are immediately cooled. With the volcano in a cup, you can see what happens underwater on a smaller, safer scale.
