By now, I think everyone has heard the myth about cellphones starting fires at gas stations. It turns out that it's not the cell phone that is the culprit, but rather static electricity. ABC News recently did some tests involving cellphones and gasoline.
no fair - MythBusters handled this first :). Darn ABC stealing ideas from the Discovery Channel. MythBusters ended up doing their actual busting by trying to ignite it with static electricity.
