[$9000] Question: what is water-propelled, goes 25mph, dives like a submarine, and sets you back nine grand? The Jetovator of course – or in more general terms, basically a dirt bike combined with a jet pack. Check the video after the jump. The Jetovator looks like about the most fun thing ever created. It can elevate up to 30 feet, dive up to ten feet, and do all kinds of tricks in the right hands. It can probably also kill you in about 2 seconds flat, so be warned.
