Soap in a microwave

Do this now:

  1. Cut a bar of Ivory soap into thirds.
  2. Place one piece in a microwaveable bowl and microwave for one minute.
  3. Remove and enjoy foamy goodness.

It looks like shaving cream, feels like sticky powder. The soap expands tremendously. It's a simple chemistry experiment that's well worth doing. This page has a lot more info; among other things, it says non-Ivory soap doesn't have enough trapped air to foam up and will just melt.

Tanya was watching a cooking show called Food Detectives and they did this and she then tried it with our oldest daughter and it was good.

If you get on YouTube you can find a bunch of videos of this.
