Oh my that looks cool

@ariachannell, if you do this one, don’t use the whole bar-cut it in 1/4 or 1/3 (a little goes a long way), put it on a microwave safe plate (like a paper plate), and don’t heat for more than 1-2 minutes. I do this every year with my students and they are amazed! Once it’s cool, it’s safe to touch (and even use to wash your hands).

@oneplusone, I’m going to try it

That looks cool
