This is a Hand Powered Washing Machine. The purpose of this project is to make it easier to wash clothing. Washing clothes by hand can be strenuous, and the soap water may soak your hands. With this device, one can rotate the device 3/4 clock and counter clockwise for about 20-30 minutes and their laundry will be clean.
