Fuel for Thought

When refueling the family car, I usually shut off my celfone, keeping in mind advice that its electronic signal would interfere with the pump and cause an explosion. I may be wrong about this, despite seeing dramatizations of such a scenario; a person was chatting on her cell next to me while I was gassing and didn't cause the pump to explode. In any case, this should not be attempted unless the "Mythbusters" show provides dramatic evidence it can be done and the FCC gives the green light.
