OH! That makes perfect sense. Great project.
There was a breakfast burrito place that operated out of a permanent food truck in Golden, and they had one of these in their patio, but it was just one side, hanging off of a 2x4 above your head, and the string was about 4 foot long. It was pretty addictive to play while you were waiting for your food. This size seems perfect. My kids would love it. I bet you they would even play if they had to eat a bite of broccoli when they lost .
