In this zany competition teachers have ten minutes to create a science activity from a special secret ingredient. This week: wire! Ezra Daly explains how he makes musical instruments out of car and motorcycle parts, then plays his Frankenbass, created from a Moto Guzzi motorcycle gas tank, a chrome tailpipe, and scrap mahogany. Next, Doc Popular (aka Brian Roberts) shows how he creates instruments by circuit-bending toys. Doc--not just an inventor and a video editor but a yo-yo champion as well--will also demonstrate some yo-yo tricks.
In this zany competition teachers have ten minutes to create a science activity from a special secret ingredient. This week: candles. 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.
