Step 1: Fill water guns with a mixture of tempera paints and water. I didn't measure anything; just tried to not make it too watery.
Step 2: Cover (or undress) your kids. Or both!
Step 3: Find a spot that can get a little messy without a lot of stress...for us that meant outside!
Step 4: Lay out some ground rules. Best to not skip this step. I did...absentmindedly, and ended up with a very Warhol-inspired right leg.
Step 5: LET THE FUN BEGIN!
* For colors from every angle, rotate your canvas/sheet/paper throughout the project. It's much easier to move materials than little bodies yielding guns filled with paint!
* Lay project flat. If upright, the paint will run down the surface.
* Have a pack of wet wipes handy. :)
