Patent ID: 7647921

Claim:
A submerging air pressure projectile launching system, comprising: (a) a device body, including a water intake and a launch structure, defining an interior air chamber, the water intake being disposed at, and having an exterior opening at, a lower end of the device body such that the interior air chamber is in fluid communication, via the water intake, with the environment that is exterior to the device body; (b) a projectile, temporarily mountable to the launch structure to semi-seal the interior air chamber; and (c) a column of water temporarily disposed in the interior air chamber and in fluid connection with a body of water in the exterior environment; (d) wherein, the submerging air pressure projectile launching system is configured such that, when the lower end of the device body is pushed into the body of water, water of the column of water temporarily enters the interior air chamber, and the temporary presence of the column of water in combination with submersion of the launch structure causes a compressive force to act upon air within the interior air chamber until a coupling force between the projectile and the launch structure is overcome, causing the projectile to launch into the air; (e) whereby the submerging air pressure projectile launching system is configured such that pushing the lower end of the device body into the body of water effects launching of the projectile into the air.
