Inventors Windell Oskay and Lenore Edman demonstrate the CandyFab 4000, a printer that creates 3D sculpture by stacking 2D images made of sugar. Drawing from disciplines as varied as circuit hacking and sewing, the sugar printer is only one of Oskay and Edman's many projects, which include an interactive dining table and hard-drive wind chimes. While demonstrating how to build an electromechanical digital clock, Jim Newton talks about different kinds of tools—from low-tech, such as a drill press or a welder, to high-tech, such as laser and plasma cutters. Jim is a lifetime maker, veteran BattleBots builder, and former MythBuster. It's geometry! It's knitting! It's—hyperbolic crochet! Artist and science writer Margaret Wertheim shows you how to represent a hyperbolic plane using crochet hooks and yarn. Beginning with a simple crochet chain, learn how to create a geometric shape with a constant negative curvature just by adding stitches. Tinkerer, programmer, and musician Ken Murphy shows how to build electromechanical "bugs" built from scavenged materials and powered with a single coin-cell battery. When the Blinkybug's wire antennae detect motion from air currents or vibrations, the bug comes to life, with its LED eyes blinking in rhythmic patterns. Watch as the best teachers on the planet battle it out for the title of Iron Science Teacher. In this zany competition teachers will have ten minutes to create a science activity. This week’s “secret” ingredient: Milk! Dr. Paul Doherty scours the globe for the world's greatest science demonstrations. Here he partners with Dr. Gorazd Planinsic, frequent contributor to Physics Teacher magazine, active in international physics education, and illustrator of physics text books.
