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.
