Ivory Soap Explosion

A few months ago I read about Ivory Soap in the microwave and I have wanted to try it with the kids.  

If you do not have Ivory Soap, get some in your next grocery trip.  I promise you will not be disappointed!  

Tip #1:  Break the Ivory Soap in 1/4 pieces. Do not put the entire bar in the microwave all at once.

Tip #2: It only works with Ivory Soap.  Tiny air pockets are formed in the soap (that's why Ivory floats).  When heated in the microwave, the moisture in those air pockets changes to a gas and expands.  (I told the kids it is similar to what happens with popcorn).

Tip #3: Be careful at first, because it is fairly hot when it first come out of the microwave. However, it cools down quickly and can be easily handled.  I thought it would be sticky or slimy feeling, but it was actually dry and a bit crumbly.

The kids had a fun time touching it and breaking it apart.

I added a bit of water to make it more "goopy".
