This modification on existing super-soaker technology uses the basic principles of one-way valves and water pressure to refill a water gun on demand. The gun is sold with a cradle that receives the gun and holds it in a prone position. The under slung nipple on the gun's reservoir will snap into place in a receiving valve to fill the tank. A one-way valve on top of the gun allows air to escape as the tank is filled, rapidly decreasing the gun's fill time from a traditional super soaker gun.
The child will use the super soaker in a traditional manner until it is empty (pumping, pulling a trigger, repeating until storage tank is empty). When the tank is empty, the child will just press the gun down into the cradle and wait a few moments for the tank to fill up.
The soaker will be made as most traditional guns, using injection molded polyethylene and polypropylene (resins have not been significantly evaluated yet). Costs should be remain around $20 per production unit, and will likely retail at an MSRP around $50. The plastics will make the product durable, but safety of high pressure water will restrict the use of the product to children capable of handling this gun, probably around 12 years or older.
