Balancing Nails Puzzle – Bigger Nails Give a Cool Twist on an Old Puzzle
It’s a really cool science puzzle… balancing a pile of nails on the head of a stationary nail. I’ve always liked this puzzle because it gets kids thinking about the center of gravity. In this video, we substituted the small, table-top version of the set-up for a dozen large nails – like the kind you would use for landscaping. Mark Koebrich was surprised by the solution, but I was surprised to see how much he liked the dumb balancing bird demo. Just goes to show you that you never know which ideas are going to stick.
its too cool my kids loooooooooooooooooveeeeeeeeeeee it
