The Flying Machine
Watering plants while flying - an interactive water game
The flying machine is a combination of a childhood dream to fly and a practical application, watering plants.
The pilot can control the helicopter by alternating the thrust of the two rotors.
It takes a decent amount of skill to control and keep it in a hovering state, because as soon as the pilot flies too high, the linkage on which the helicopter is mounted on is pushed together, locking its altitude at maximum level.
As soon as that happens, a valve is opened and the only way to pull the linkage apart again is to fly at maximum speed. While the levers are being pulled apart again by centrifugal force, the plants underneath are continuously watered.
