Ivory soap is manufactured with pockets of air. Not only do these air pockets allow the soap to float in water, they make for an interesting experiment with a microwave.

As the oven heats the soap, the pockets of air expand. This is the result. Use a new bar of soap and heat it for 60-90 seconds. You also might want to heat only ⅓ or ½ the bar. See the video in the next slide.
