World Maker Faire

The spelling may be old-fashioned, but the ideas are all 21st century in this festival of do-it-yourself science. First presented on the West Coast by Make Magazine, the fair is coming east again to the New York Hall of Science, which will showcase hundreds of projects combining craft and technology. This year’s highlights include a Fly Zone, with hand-built rockets, airplanes and drones; shows of shooting geysers made by combining Coke Zero and Mentos; a 3-D Printing Village, a Fix It Village and a Lockpick Village; how-to tech workshops; circus arts; and the ever-popular life-size version of the Mousetrap game.
