Watch this video in which popcorn is popped by surrounding it with cellphones that are turned on at the same time:
Is this real or a hoax?
Not a chance. Cell phones don’t emit more than a watt (it’s actually much less, but I’ll be generous), and since the radiation from the phones goes in all directions and there’s no enclosure to contain it, only a tiny fraction of that is being absorbed by the kernels. It’s completely fake.
Snopes has debunked the “cooking an egg between two cell phones” urban legend, which amounts to the same thing, and recently extended it to include the popcorn legend as well. Bottom line: Not only false, but a viral marketing scheme cooked up (uh, pardon the pun) by Cardo Systems.
No way Jose, er Dave,
I found this I hope it helps.

Video to demonstrate how you could make it appear popcorn is popping on an open table.
Edit: to say the video is safe for work but that site has some NSFW stuff.
