Popcorn via your cell phone.
 

You believe it?

Yes, I do. Have seen multiple videos of this "trick". Some of the participants have been way to dumb to have faked it ;)

I showed this video to a friend at his work a few weeks ago for a quick laugh, his manager watched it also... became instantly obsessed with doing it. Collected about 6 cell phones from around the store's employees and called them with her phone on conference call... not a damn thing! Just as much of a hoax as the "make mountain dew glow" shit. The most entertaining aspect of it to me wasn't her trying to explain why she wanted everybody's phones... but all of the retarded ring tones going off at once! Not a normal "ring" in the whole bunch.

Read about it on Snopes or similar sites. It is a viral add for Bluetooth headsets.

In the meantime, this is a funnier version: Yes He Can - It's Time for Change!
