I might add it takes approximately 2 minutes of speaking on a cellular phone for the radiation to cross the protective Blood Brain Barrier. So whenever there is a landline available, use it in preference to your cell.
Vladimir Lagovski and Andrei Moiseynko from Komsomolskaya Pravda Newspaper in Moscow decided to learn first-hand how harmful cell phones are. There is no magic in cooking with your cell phone. The secret is in the radio waves that the cell phone radiates.
The journalists created a simple microwave structure as shown in the picture. They called from one cell phone to the other and left both phones on talking mode. They placed a tape recorder next to phones to imitate sounds of speaking so the phones would stay on.
After, 15 minutes: The egg became slightly warm.
25 minutes: The egg became very warm.
40 minutes: The egg became very hot.
65 minutes: The egg was cooked. (As you can see.)
Conclusion 1: Cooking eggs with mobile phones is possible but very expensive ($4.55 or 123 Rubles)
Conclusion 2: All this talk of danger is exaggerated; even if your brain gets cooked, it would take a couple hours of talking on a cell phone.
Conclusion 3: We do not recommend carrying cell phone in your pants.
