Painting with Watercolors, Glue and Salt. This will be a fun project this summer, just paint the canvas with watercolors. add some kosher sea salt (coarse is better than fine salt) and some glue splotches!
Fun art project with the kids! Easy abstract painting that anyone can do! Just blob the paint on the canvas in random spots and blend! (would be interesting how students could make different pictures w/ the same colors and same blob positions)
