Abstract: Disclosed is a device which incorporates a process by which an absorptive material is used to absorb fluid, the weight of said fluid causes the device to move without any outside energy source. The fluid, by way of evaporation or by being absorbed into another absorptive material, substantially disappears, causing the device to return back to its starting position on its own, and repeat the process. The fluid, which is stocked in a holding area, remains stagnant, until the device in its starting position is made in contact with the fluid by use of a counterweight, and thereby absorbs the fluid, however, when the device is saturated, the greater volume of absorbent on one side causes the device to move to its activated position. In its activated position, the device is not exposed to the fluid and therefore remains until the fluid is evaporated or absorbed into another absorbent.
