DIY Japanese Air-Powered Jet Pack

This video features Japanese people doing something they seem to be very talented at: doing weird stuff. In this case, a some guys strapped a bunch of soda bottles together, pumped them full of air with a bicycle pump, and strapped them to the back of a retarded young man volunteer. When triggered (somehow), the man becomes airborne from the thrust generated by this homemade jetpack.

Variations on a theme

A big shout out to Grimbot at DM.net for the model sheets.
