==Handwashing made simple — the Tippy Tap==
If you don’t have a tap, washing your hands in a hygienic way isn’t easy. You could place a bowl of water on a table, but then you would be washing your hands in the dirty water other people left behind. You could walk to the hand pump and ask somebody else to pump while you wash your hands. But that needs two people and wastes a lot of water. Can we do better?
