water-proof song box and, just as our nerves began to settle from the excitement, someone came along and dropped this eco-friendly, shower-ready gem on us. Not only is the H2O Shower Powered Radio waterproof, but it actually uses the water from your shower to pump out the jams. The thing connects directly to your shower hose, and uses the flow of water to set a micro-turbine spinning, thus charging an integral battery and eliminating the need for disposables. As the video below points out, the radio "doesn't just offer 80s classics -- it has the full spectrum of FM," and its creators say it's compatible with 99 percent of showers, but what we really want to know is: how well does it crank the Ke$ha?
