After Ghana went under lockdown at the beginning of April, a pair of brothers built a unique invention to help citizens of Kumasi stay safe. It's a solar-powered hand-washing basin, with a very nifty feature.
A timer complies with the CDC's suggested 25-second hand washing cycle. The device releases soapy water when hands or other items come into contact with a sensor underneath the faucet. After 25 seconds, an alarm indicates hand washing is complete and clear water is released to rinse hands before drying. With days, Ghana's Ministry of Environmental Science contacted the brothers to see if more machines can be made for other cities throughout the nation.
