Bowls made of confetti! Great recycling art project--save all those leftover paper scraps (put in small bowls at each table). Collect a bunch and have the kids cut them up; Then make bowls made from confetti.
Melted Crayons combined with pictures. it would also look cool to put only black at white pics in the middle.like the color exploded from the pictures>>>>>> or if you did shades of black grey and white crayons with black and white pictures
