Nine-year-old Kenyan Stephen Wamukota has invented a hands-free hand-washing device that is operated using foot pedals and is made entirely out of wood, reports China Plus South Africa.
The invention, which requires no electricity, has two pedals. Pushing down with your left foot sets off a mechanism that distributes liquid soap from a squeeze bottle.
Then, pushing down on the second pedal with your right foot turns a water container, allowing you to rinse the soap off your hands.
Another container collects the dirty water so that it doesn’t spill at your feet.
Stephen revealed that after seeing how toy cars are assembled on TV, he realised he could produce a similar mechanism, but for hand-washing.
