Saw these instructions for a light box on Facebook and made one in less than 30 minutes. I had everything I needed to make one. A box, 3 pieces of tissue paper, tape, two pieces of white paper and two lamps. If I were going to be serious about it I would use a bigger box, brighter bulbs and set the box where an over head light were closer. But for free and easy I thought it worked great and here is the link. There are some really neat things on the Facebook page, techie science inventions.
