Volcanoes!

Such a simple "science experiment." Yet, so much fun! Allison actually picked this one out of her "craft" book, and I thought she'd be disappointed that it wasn't really a craft. I was WRONG! She actually had a blast with this and played for quite a while. It's just baking soda, and vinegar with food coloring. (Food coloring, optional!) And, as you can see, it has a sort of volcano effect! One word of advice, though. Clean this up right away, or it becomes a sticky MESS!
