That is a very unscientific statement.
Please show your physics before you patronisingly spit at me for even
considering the problem. Obviously, the size of the object heated is
of considerable im****tance. A shorted dry cell gets plenty hot.
To pop a single kernel of corn would take considerably less than the
amount of energy needed to convert an equal volume of water to steam.
I don't think you can't categorically dismiss the question without a
little back of the envelope math. In any case, I get really really
annoyed with folks who try to squash curiosity in others. There is
nothing wrong with asking questions even when the answers (including
the wrong answers) are "obvious" to some.
I hope you don't have any kids.
As a ballpark, I will guess you need to va****ise a milligram of water
to pop a kernel.
The latent heat of va****isation is 2260 joules per gram.
So I would need roughly 2 joules to pop one kernel.
A joule is a watt-second.
You can get 3 watt cell phone boosters, but most cell phones are about
1 watt according to
http://electronics.howstuffworks.com/cell-phone-radiation1.htm
If you put three of them together you would have available 3 watts.
Presuming all the power went into the heating the kernel, I should be
able to pop a kernel within a second.
So I think an experiment is in order to see if this is a hoax, after
you check my arithmetic of course.
