You’ll find 8 different examples of crushed can crafts the kids can make over at about.com. Just cruch the cans good and flat and turn the kids loose with their paints. I’d suggest using acrylic paints as they cover nicely but also clean up with water. Click on each picture on about.com and you’ll be taken to complete instructions and complete supply lists.
This fun craft would work well at a girls birthday party as well as at home. Gather up the supplies and print out a picture of each of the 8 examples. Challenge the kids to come up with other creations using their cans. Should keep them happily busy for a good 1/2 hour!
