Disclosed is a water sampler and method for dropping the water sampler from an airplane to obtain a sample of water from a body of water; the water sampler comprising a tubular member with ball valves at both ends and an open ended canister disposed between the ball valves, a line connected between the airplane and the tubular member for yanking the tubular member through and from the water, the yank of the line being used to move the ball valves from an initially open position to a subsequently closed position, the canister thereafter being capped and removed.

A method of collecting a water sample comprising: providing a tubular member with a pair of open end tube portions, each of which contains a ball valve rotatably mounted between an inner valve seat and an outer valve seat; setting said ball valves to an initially open position to receive said water

A method of collecting a water sample comprising: providing a tubular member with a pair of open end tube portions, each of which contains a ball valve rotatably mounted between an inner valve seat and an outer valve seat; setting said ball valves to an initially open position to receive said water sample; attaching a first line between an airborne moving object and said tubular member and dropping said tubular member from said moving object into a body of water so that said tubular member submerges into said body of water and causes a yank on said first line; and using said yank of said first line to provide the force necessary to rotate said ball valves to a closed position.
