An amazing vision

Every once in a while you hear of a man or woman who is doing incredible work in a particular area. Do you remember the Michael Pritchard's water purification system? In this case, it's Josh Silver. In this Ted video he demonstrates his invention - eyeglasses that you create yourself. They currently cost about $19.00, but, he says, that's too much when you're talking about a billion people who live on less than a dollar a day. Watch this video and see if you don't find yourself shaking your head in wonder and the amazing talents of some people.

Will one of YOUR students be the next person to invent something that will have such an impact on the world?
