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.

Ice Stories:  Static Scarf (Clip)
Running Time:
00:00:28
The air is so dry here at McMurdo that anything that gets charged, stays charged. Moist air quickly discharges objects because the water in the air picks up charge from an object and quickly flies away, taking charges with it. This does not happen here. We are constantly getting shocks from our clothing, our bedding and when we exit vehicles.
