Fizzy Rainbow Science

I found this idea at Play Create Explore and thought it would be fun for the kids.  Plus, it worked as a great St. Patrick's Day activity.  Camden has already asked to do it again.  He pretended it was a big volcano field with lots of erupting volcanoes.  The red was the hot lava and the gray (which was supposed to be more purple) was the ash.  They both had so much fun watching it bubble up and fizz.  Ciera also loved all the smells it created.  It really did have an intensely sweet smell.  She just kept sniffing it and pretending to gobble it up.  It is made with just several Kool-Aid flavors, baking soda, and vinegar.
