Soap Souffle!

Ivory Soap is the soap that floats! It contains air pockets. The microwave heats the air and water inside of it. The water vaporizes and the air expands, changing its physical state. You can conduct an experiment with Ivory Soap and another bar brand. Ivory puffs due to the air inside, while others will simply melt. (Microwave for 90 seconds to 2 minutes on a plate). Another experiment you can try is testing Ivory soap against another bar brand in a bowl of water. Ivory will float, while others will sink. You'll need 2 fresh bars of soap. Legend behind floating soap @ Ivory. For more science behind the experiment visit Steve Spangler!
