The Eco Egg Washing Machine will delicately handle even your most fragile, lacey underthings, using "gentle agitation" in lieu of the traditional agitator. It's been around since 2003, but Shiny Shiny covered it and I couldn't resist. Definitely the most fun washing machine to pretend you're an astronaut in, it's available from Amazon for just $75, and can plug right into the kitchen faucet in your studio apartment. The big downside: There's no spin-dry, so you have to hand-wring your clothes.
