This is not exactly a "funny" but it was fun! We have visted the children's museum in our town many times and I could never get my children to experiment with this one display. They are plastic rods that slid from one side to other when you push on them. On our last visit, I couldn't get them to stop...they were doing every part of their body...and I mean every part they could!! Check out this video of Miss and her Daddy!
