Water jetpack may be man's greatest invention to date

Somebody tell me where I can get one of these. RIGHT. NOW. Seriously, how awesome is this? It's a jetpack, but it uses water to propel you in the air. You're tethered, but can still get pretty high/far, and you just drop into the water if something goes wrong. It solves all of the problems of regular jetpacks!

If they put this thing up for sale, it'd be the ultimate toy of the lake mansion set. Inflatable trampolines? Please, those are for poor people. The real fun is with water jetpacks. Seriously, I want one so, so badly.
