A tippy tap is a water-saving handwashing device developed for use in areas where there is no running water, usually fabricated out of simple found materials. Erik and I both love appropriate tech, and this is a really good example of the form. The tippy tap literally saves lives by allowing people to wash up after visiting the bathroom.
Erik included a tippy-tap, a rather fancy version of one, it turns out, in one of our link roundups. I’d never heard of such a thing, and, intrigued, promptly fell down a deep YouHole watching tippy-tap videos.
The basic idea is that a jug of water is suspended from a pole or branch by the handle–so it can tip. A string is then tied to the top of the jug to act like a lever to create the tip. A small hole punched in the front side of the jug allows a thin, controlled stream of water to flow when the jug is tipped. To keep cross-contamination from occurring, you don’t actually touch the jug or the string to use it. Instead, the string which tips the jug is tied to a stick on the ground, which acts as a foot pedal, so the jug is tilted by foot action alone.
I thought it would be cool to have a tippy tap hanging in the garden for hand washing — better than spraying water all over with the hose, especially in these times of drought. It would also be a good handwashing station for camping. So I made a beta version to test the idea. Long story short, it works well. I made a few mistakes and want to work out some kinks. Also, for use in the garden, I want to design a more attractive tippy tap, perhaps using a gourd or ceramics.
