Make Vol. 20 features a season's worth of how-to projects that kids and their parents can build together, including a model rocket powered by hydrogen and oxygen extracted from water, a sleek wooden model sailboat, a laser light show built in a metal lunchbox, and a microscope based on the very first one ever built by Antony van Leeuwenhoek in the 17th century. If you're looking for a prize-winning science fair project, or just want to have fun, this special For Kids of All Ages issue of Make has something for you! http://Makezine.com (less info)
