Abstract: In an aspect, an inflatable object includes an object body enclosing a chamber to receive air, and a valve mounted to the inflatable object body, including a valve body defining a passageway between the chamber and an ambient environment. The valve body has a shoulder. The valve body defines an outside end, which opens to the ambient environment, and an inside end, which opens into the chamber. The valve includes a one-way flap that is movable between an open position to permit fluid communication between the chamber and the ambient environment through the passageway, and a closed position. The one-way flap is biased to the closed position with a closing force selected to be overcomable to move the one-way flap to the open position by an airflow having a speed that is less than about 48 m/s, and which is at a pressure lower than 1 atmosphere.

Abstract: An improved siphoning device having an elongated hollow body member having a first open tip end with a fluid flow opening and a second open end. A two-way liquid valve is positioned within the first open tip end, and air pump member is removably attached to the second end of the body member. The seal member is movably positioned within the first open tip end. An air vent exhausts hot gases and is an air outlet for pumping air out of the body and creating suction within body. The air vent is preferably positioned proximate the elongated body second open end and has a cross-sectional area substantially less than the fluid flow opening cross-sectional area. The air vent preferably has a diameter in the range from at least one thirty second of an inch to three thirty seconds of and inch. Most preferably the diameter is greater than one thirty second is of an inch and less than three thirty seconds of and inch. Most preferably the diameter is about two thirty seconds of an inch.
