Watch these three unbelievable videos, below:
And people laugh at me for using my bluetooth headset with my mobile phone as much as possible. I still do not trust the safety of cellphones.
In the meantime, I'm going to try to make popcorn with my cellphones and see if it works for me.
UPDATE: Wired magazine's blog is claiming that these videos are a hoax.
The clever parlor trick looks amazing enough, but there's a hitch: It's not physically possible, according to University of Virginia physics professor Louis Bloomfield.
"[The videos] are cute," said Bloomfield in a phone conversation Monday. "But that's never gonna happen."
In a microwave oven, energy excites the water inside popcorn kernels until it turns into highly pressurized gas, causing the kernels to pop. If mobile phones emitted that much energy, the water in the fingers of people holding them would heat up.
"It would hurt like crazy," Bloomfield said. "Cellphones probably warm your tissues, but studies indicate that's not injurious."
Bloomfield, author of How Everything Works: Making Physics Out of the Ordinary, dismissed theories bubbling up in comment threads about the videos that suggest harmonious vibrations are heating the corn.
"Ringing the phones doesn't help because they're interfering with each other and receiving a signal [from a cellphone tower] -- not transmitting it," he said. Furthermore, while it is possible to heat with sound, it's not likely to happen at the low volume emitted by a mobile phone. "It would be like gathering opera singers together to sing, and trying to make the corn pop," Bloomfield said.
