Science in the City: Electric Guitar (Clip)

Running Time:
00:09:30

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.

After Dark: Dr. Megavolt under the Palace of Fine Arts Rotunda (Clip)

Running Time:
00:02:54

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.
