It's like a grade-school science project you can ride, but with severe consequences if it goes wrong.
On the rocket trike, which you can see in the video above, Gissy managed a top speed of 162 miles per hour (260 km/h) at Circuit Paul Ricard. Perhaps even more impressive (or frightening, depending on how you look at it) are the acceleration figures. The trike did 0-62 mph in just over half a second (0-100 kph in 0.551 seconds). Gissy covered the first 60 feet in just 0.852 milliseconds, pulling an average of 5.138 g in that same distance.
If you want to see a bit more footage from the water rocket trick, this video has more angles, and a mesmerizing, slow-motion clip of the launch:
Gissy has also built and tested a rocket bicycle, which he rode to an alarming 207 mph in 4.8 seconds. He's currently looking for sponsorship to build even crazier vehicles. We hope he gets it.
