Hydrocycle from polyfoam a water-cannon from a motor-pump. Fly away on the water.

I embody my ideas with my own hands. I conduct tests of my inventions. I share with all who are interested. The hydrocycle made of polyfoam, a water-jet from a motor-pump, a wheel for a water-jet from a plastic pipe. Simple design, available made in the garage. You can work with the design. The first tests and manufacturing process.
