My son is thinking about competing in a science fair this spring. I can tell you one thing -- science fairs are not what they used to be in the 70s and 80s. Just look at what's out there now.

Can you imagine your own 3D Printer to make your own, well, anything? Download a coat hook design and print it yourself in any colour or size. Yes, Virginia, possible. Today.
