"Plausible? Let us do a little math.

Popcorn pops because the water in it turns to steam and a kernel is about 14% water. So, if we assume a kernel of popcorn weighs 1 gram, it has 0.13 grams of water. Heat that water from 30�C to 100�C would take:

(0.14g)*(100�C-3 to turn the water to steam requires he latent heat of vaporization, which is 2259J/g.

2259J*0.14g= 316J
for a total of 316J 41J = 357J.

Wattage = Joules/seconds. If it took about 5 seconds to turn the water in the popcorn kernel to steam, then the wattage required was:

357J/5sec = 71W assuming all power from the cell phone transmitter went into the kernel.

Cell phones typically have 0.75W-1W transmitters in them. With a 1W transmitter, it would take,

334J/1W = 334secs, if all power is transfered to the kernel.

You decide."

You can't argue with mathematical law.
