Can you make popcorn using cell phone as a source of “microwave” activity?”
A cell phone usually emits about 1 watt. You’d need a thousand cell phones to be as much as an ordinary microwave. Even if you did get that many, it wouldn’t help. The frequency is wrong. Microwaves operate at 2.45 GHz, which is designed to have a resonant frequency with water molecules. The lower .8-.9 GHz frequency used by cell phones isn’t as effective. And even at that you’d need to find a way to direct the radiation into a microwave-reflective cavity, like a microwave oven. I suppose that feat might be possible; it would look like a box with a thousand cell phones sticking out of it with their antennas inside. It would leak radiation like a sieve, I suspect. A few dozen cell phones might be able to make a chocolate bar slightly softer. Maybe.
