Bar of soap in a microwave. This is a particular type of soap that has air whipped into it. This makes it float in water. When heated in a microwave the water trapped inside the soap vaporizes and the trapped air expands. The soap also softens. These physical changes cause the soap to expand and form a rigid foam. Soap that does not have air whipped into it would melt in a microwave. For images showing the expanded soap see C019/4406 and C019/4407 | |
