How to Build a Tippy Tap
The tippy tap is a hands free way to wash your hands that is especially appropriate for rural areas where there is no running water. It is operated by a foot lever and thus reduces the chance for bacteria transmission as the user touches only the soap. It uses only 40 millilitres of water to wash your hands versus 500 millilitres using a mug. Additionally, the used “waste” water can go to plants or back into the water table.
