I was recently scouring You Tube when I came upon this contraption. I would almost consider this more gadget crack than I would design crack. Still, the design that lead to this invention was immense, I’m sure. So, I commend you oh inventor of the Projump stilts. What’s the big deal though? You’d have to see it to believe it. Check out some of the videos here. The design creates a true extension to your legs’ abilities. You can run, jump, and move nimbly in these stilts. It’s prety amazing because at first glance it would look like this contraption would immediately snap your bones in half. Not so, it seems.
