Ivory

We did a fun experiment last week with Ivory soap (must be Ivory). We halfed one bar (must be halfed). The boys took turns and we put it on some paper towel and in the microwave for a minute. It grew and grew! It was fun to touch and feel. The only downside is that the smell of the soap gets pretty strong while it's warm and it was a little too strong for me. Fun quick experiment on a boring day but make sure you get some hypotheses before you start!
