Painting with Watercolors, Glue and Salt. Kids will love being creative and making designs with the glue. The salt creates a pretty starburst effect by soaking up paint pigments as the painting dries. And as an extra bonus: the salt sparkles!
Paint holder: two wire shelves from one of those wire shelving units and zip tied empty thread spools in all four corners and the middle to keep them together, yet spaced apart enough to hold craft paints (kind of wine rack style).
