I took was trying to make paint from a powder. I accidently made it too thin, but then it looked like watercolors. My kids had a blast here are some of their creations. Dragon made "Nothing" and a Ferris Wheel.
Tracker made a Pokemon.
Squirrel made a beautiful Rainbow.
Th is is what happens when you try and clean up the painting fun by putting all the cups in a paper bag. Even 2 days of rain hasn't made it completely disappear.
