Travel Spotting: Trampoline Bridge in Paris

I have never understood why trampolines weren’t a valid form of transportation. Why would you want to walk somewhere when you could jump there? Apparently, French architects in Paris share my sentiment because they are proposing a trampoline bridge to span the width of the Seine river. The trampoline bridge would be made of PVC pipe inflated with pressurized air. It would make the walk to work a lot more interesting and surely be a huge tourist attraction for the young at heart.
