Mobile cooking: how to cook an egg with 2 mobile phones, an egg cup, and a radio. Or, why you shouldn't talk on two mobile phones at once. UPDATE: OK, not really. "The radio waves from mobile phones are at least 100 times too weak to heat up an egg, they're at the wrong frequency to make water molecules vibrate, the antennas on mobile phones are directionless, and when you call one phone with another the (omnidirectional) signals are relayed via radio towers rather than directly." Thanks, Harlan! I <3 the Internet.
