In mimicking the curious action of milking a cow, I saw an opportunity to improve the way people do the washing up.
The Udder can be retrofitted to most domestic kitchen taps, and creates a jet of water to get the grime off dirty dishes. To turn on the water, just squeeze the Udder, just as if you were milking a cow. As soon as you let go, the water stops. The valve is designed so that you only use the water you need, rather than leaving the tap running.
It's a fun way to decrease water bills, help save the planet, and get kids to do their chores.
