Stirring Mechanism

The purpose of this device is to stir the chamber water to keep it from becoming stagnant. The magnet shown in the picture is attached to a battery which is attached to a lid (bottom). It sits inside of a chamber at the bottom of the Lander. The spinning magnets magnetic field influences another magnet attached to a paddle inside of the testing water. Turning the water allows oxygen to continue to get consumed rather than just the bottom oxygen getting used up.
