There’s no mistaking the distinct voice—whether throbbing, singing, or screaming—of an electric guitar. How does one instrument produce so many different sounds? We visit with Bay Area electric guitarists Ava Mendoza and Henry Kaiser, plus Subway Guitars’ very own Fat Dog, to explore the components of this versatile instrument, getting down to pick-ups, “pots,” and pedals that make it sing. Staff educator Modesto Tamez tells how he gets students exploring electromagnets, a great preparation for making an electric motor. In November 2009, Exploratorium After Dark welcomed particle physicist Dr. Austin Richards—aka Dr. MegaVolt. Under the Palace of Fine Arts rotunda, he jousted with a high-voltage Tesla coil, which generated 200,000 volts of electricity and shot 14-foot-long arcs of lightning through the air. Meet Dr. Ethan Brodsky from the U. of Wisconsin, who advised a group of undergraduate students in the design and build of an electric snowmobile. Video produced by Ice Stories correspondent Zoe Courville. An introduction to the jitterbug, a simple motorized toy made of a recycled CD and a DC motor. A detailed demonstration of how to make this toy, including a discussion of materials needed. The science behind this toy, including a discussion of how electric circuits work, and how an unbalanced load (an off-center weight on your jitterbug) results in rotational vibration. Dr. Jim Tour, a chemist at Rice University, builds the world’s smallest vehicles. He calls them “nanocars,” and he thinks these tiny vehicles might lead to nano-sized factories. We’ll also hear from University of Florida graduate student Diane Hickey, who will tell us some of the interesting reactions she’s run into when explaining nanotechnology. Exploratorium Senior Scientist, Dr. Paul Doherty, takes us through the Photoelectric Effect and the "invention" of photons. 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: Pencils
