Make your own pinhole camera to safely view a solar eclipse in action! (NEVER look directly at the sun without proper solar filters!) Plus get ideas for turning these stellar events into an art project you can keep long after the eclipse is over.
This is just the neatest, smartest thing. First, hollow out an egg with a hole on the side, put photographic emulsion on the inside, cover the egg, take it outside, then allow the egg to be uncovered. Then you take it back inside, develop it (it's easy - the author explains how), remove part of the shell around the pin hole, and voilà! You have a photograph *inside the egg on the shell*.
