The human projectile. "This cannon uses you as a human projectile. Turn into a bullet and be catapulted by a high pressure waterjet up to 10 metres into a landing pool. This will give you the ultimate thrill making you feel like the wiley coyote sitting on a rocket chasing the road runner." That is how some of our clients advertise this thrilling ride. A technical note: the landing pool has to have a depth of at least 3 metres, even though our specially developed safety system is in place and can be activated by the user him- or herself.
