We’ve all dreamt, with tears in our eyes, of one day flying with a jet pack. The inherent danger of ... a pump that drags along behind you pushing water through nozzles on your back.

The device itself was made by Franky Zapata, of Zapata Racing, the makers of the earlier ‘Flyboard’ – a water-powered jetpack-like device worn on the feet and attached to a jetski – see bottom video.
