So there's a new shower head that's blowing up on kickstarter, with the backing of Tim Cook. They installed these things in a Silicon Valley gym for people to try out and give feedback. Tim Cook happened to be working out there at the time. He tried it, and liked it so much he became an investor.
It produces water droplets that are much smaller, like a steam shower, but is still powerful enough to effectively rinse out shampoo. They sold 20,000 units of their old model at $500. This is now their mass market model, and will be $200 (but is $180 on kickstarter).
