Ivory Soap Foams and Expands In an Experiment Filmed Inside an Active Microwave

Science presenter Steve Mould filmed Ivory soap foams and expanding during an experiment he filmed inside an active microwave. Mould says he will be using the new recording technique to perform other microwave demonstrations in the coming weeks.

I figured out how to film inside a microwave without destroying the camera. First video is of ivory soap. The bubble of air inside expand to create this cool effect.
