Microwaving Ivory soap


Yup.  I was shocked too when I saw the results.  But it really works.  We tried making this puffy soap with a friend.  Chuck didn't seem too excited by the transformation, but his friend loved it.

I just took a bar of Ivory soap, cut it into quarters, placed the pieces in a bowl, and microwaved for 2 minutes.  (Note: It's got to be Ivory soap.)

Why did it expand?  Well, unlike other brands of soap, Ivory soap has a lot of air inside. As you heat the soap, the water vaporizes and the air expands, causing the soap to poof out.  (See Steve Spangler for more information.)

I had to wait a couple of moments before I could touch it because parts were pretty hot.  The texture reminded me of crumbly cotton candy.  As we played with the soap, it slowly broke down into a fine powder.



You can still use it as soap... but I'm going to use the soap powder for another reason....homemade laundry detergent!
