Soap fun

I kept seeing a science experiment using Ivory soap on Pinterest.   One day while I was at the store I saw the soap by chance and thought I would give it a try.  The girls really loved it.  Who knew that if you microwaved the soap, it would grow and expand!?  Afterwords, we decided to try to make the soap crumbs into bath paint.  I found that idea here http://www.housingaforest.com/fluffy-bathtub-paint/.  It didn't work out so well for us only for the simple fact that we let it sit for a few hours instead of using it right away-duh.

First up:  open soap and put it on a microwavable plate.

We heated the soap 30 seconds at a time until it was done expanding-total 2 minutes or so.

We examined it by touching, smelling, etc.  Make sure it is completely cooled.  I found a small hot ball of soap in the middle of both puffs.

These were our observations

We broke the soap into crumbles and added it to our mixer.  I added boiling water to the soap.  See the above website for complete directions. 

We then added food coloring to the mixtures that I poured into small bottles.

The paint would have been perfect for the bathtub if we had used it right away.  We waited until bath time though and it had hardened back up.  I spent time trying to "remelt" our soap.  Oh well-lesson learned.
