I thought I'd share this really cool activity at Milwaukee Museum of Art. If you go to the Illusions: Near and Far exhibit you'll find the stop motion booth where you and your kids can have fun moving images around to make a stop motion movie. If you upload your mini movie, you'll receive an email with a link to your film on Youtube!
My kids had blast with this one and the Folk Art exhibition was also really fun for them. Plus, kids under 12 are free everyday!
