I found this idea this week and had to try it.
(You can see the original pin here: http://pinterest.com/pin/123426846008168371/)
You start with a regular bar of Ivory soap. (Fresh apparently works better.)
Put it on something. The original post used paper plates or waxed paper. I used a plate.
Then put it in the microwave on high for about two minutes.
Something about the heat and chemicals in the soap makes it "explode."
It kind of poofs like "moon sand."
It's messy, fun and really laughter inducing. Warning it's crumbly and "smush-able" so you can probably shape it into a mold (for a later bath time!)
I ended up using the soap to make another batch of laundry soap.
Another look: before and after!
