Water Powered Jet Pack Wipes Out On Live TV

This video is awesome for two reasons.  The first reason is because there is a water powered jet pack in it.  That's freakin sweet.  The second reason is because it's one those live TV eff ups that are awesome and awkward at the same time. 

How long have these water powered jet packs been in existence? And can you get one with lasers guns?  Because if so, I'm pretty sure Flint might have a new superhero.
