I will be the first to admit that this is one super cool, fun science experiment!
Here is what you will need:
- Ivory soap (It MUST be the brand name IVORY soap. Other brands will NOT work! It must be a fresh bar too.
- A microwave
1) Take one bar of Ivory soap and cut into half then in half again. Place one piece of the quartered soap in the microwave.
2) Set microwave for 3minutes (even though you won’t need that much time) and push start.
3) Sit back and watch!
After about 90seconds the soap will expand to about 6 times it original size!!! It won’t be too hot to touch either. Let it sit for about a minute or two and then remove it from the microwave and watch for their reaction.
I will admit that I wanted to see what would happen to a FULL bar of soap….learn from me…don’t do it…fight the urge! I had to stop it before it finished because my entire microwave was FILLED with Ivory soap!
The soap still works the same, so don’t toss it. I placed ours in my son’s bathroom and he loves to snap off a chunk each time he takes a shower.
