Meet Francois Gissy. An extreme sports athlete who builds incredible gadgets, including this water-powered rocket trike that does 169MPH at the track. Let that sink in...

169 miles per hour on compressed air and water... That's a 0-100 in just over half a second! Just look at that launch! It did not look like fun. It looked like whiplash!

Anyway, the next time your circle of friends burnout starts talking about cars that run on water, send 'em this. It'll blow their mind.

Also, check out Francois on his Facebook and YouTube channel. It's full of neat little tidbits.
