Wikipedia tells me that Charles' Law is an experimental gas law that describes how gases tend to expand when heated. And what I did with a bar of Ivory Soap is supposed to exemplify that law.

I'd heard this was true and I'm sure mine isn't the only video of a bar of Ivory in the microwave roaming around on the Internet.

Not in 2014.

But I wanted to try it. And it was fun. And wild. And the end result looks delicious...and...smells like Ivory Soap.

(Below, I've attached a second video that gives you a little better look at the big Ivory Soap foam mound, for lack of a better term.)
