Cool, but I like the idea of the kite-rafts that you drag behind boats better.

In the video it didn't look like a boat with a pressure washer was chasing it, it looked like the motor for the pump was in an unmanned raft that the rider was pulling.  If that were the case, then you could potentially modify the raft to allow a passenger, cooler or both.

An inverted Seadoo pumping water in the hose instead of jetting out the back.

What of the sealife where these jets start powering up?
What happens if a gust of wind pushes over the occupant?
Does this work underwater?

If so you can get to find out if that Casio watch does shatter at 100m...

Ummon:
Um. wow. Next.

When you force water to take a U-Turn under high pressures, it generates some pretty weird physics. In any case, the first thing this reminded me of is the toy at the start Titan AE.

I can honestly say no I have never thought of that. When I was a child I did however think of the idea of making my own parachute out of a sheet, a life preserver and some rope.... didn't quite work the way I intended when I took that flying leap off the roof of my friends garage  :dizzy:
