Shake Light
Just like that annoying infomercial, “using faraday’s principle… bla bla bla”, you can make a flashlight that is charged by shaking it. It’s kinda interesting too that one of the store bought models they opened up was built to run on batteries and just look like it got charged by you shaking it. Don’t be fooled by imitations, do it yourself. (via)
