This guy has redirected the water output from a jetski through nozzles on a jetpack. This is an amazingly awesome idea that I am surprised no one else had come up with yet (or had they?). I think you could do the same thing on land using a firehose or some other high pressure water source. This video makes it look like SO MUCH FUN, a jet pack that doesn’t run out in 30 seconds. Who cares if you can only go 25 feet high or so.
