François Gissy’s hobby is to build insanely fast rocket bikes. His latest creation is a rocket trike which is powered only by compressed air and rainwater. It’s like a grade-school science project you can ride, but with severe consequences if it goes wrong.

The water is under pressure of 431 Bar in the tank and once Gissy opens the valve, that innocent rainwater is the most powerful drive we have ever seen.This video was shot on the Circuit Paul Ricard located at Le Castellet in France.

Many of us had the opportunity to launch small rockets made from soda bottles filled with water and compressed air. Using this very simple principle and with some rainwater, I have reached 261 km/h (162.2 mph) on a homemade trike.

While accelerating from 0 to 100 km/h (62.15 mph) in 0.551 second (the average acceleration during the first 852 milliseconds, which was the elapsed time needed to cover the first 60 feet (18.288 meters), was 50.3868 metres per second squared or 5.138 g).
