This is how it's done!

We found some kids to play with today. They had made a chain out of rubber bands and were jumping over it from side to side. They would hook their foot over one side then stretch the chain so their other foot could make it over. The kids would begin with the chain at ankle level and kept moving it higher. This 11 year old was one of the best at the game; he made it over even when the chain was at my chin.
