There are your average gadget-toy Christmas presents like an iPhone controlled helicopter or a rolling robot camera, and then there's a jetpack. Firebox has put the JetLev Flyer up for pre-order, which propels you 10m high at up to 22mph just using water.
The jetpack uses what is essentially a high-powered fire hose connected to a boat-like motorised pump, which propels water with enough force up the tube and out of the pack to fire you into the sky. Simple fly-by-wire controls allow you to rotate the two nozzles forwards and backwards to get you soaring, while you tilt to turn.
Sounds great, but there's a catch -- it's £115,000, though it comes with free delivery. If you're made of money and want something a bit out-of-the-ordinary for Christmas, point your loved ones over to Firebox or check out the rest of their Top 10 WTF gifts. [JetLev Flyer via Firebox]
