Here is the link

What do you think about the video(s)?

I don't think they are real because a couple cell phones shouldn't put out enough power to significantly heat kernels of popcorn.

The editing is pretty bad

And still apparently everyone is unquestionably assured into it.

Totally fake, popcorn does not shoot vertically straight up every single time. Also on a more realistic note, only the 3G/4G cell phones fall around the 2GHz range, and even then, they do not emit the exact 2.45GHz required to couple with and heat the water inside the popcorn kernels.

Even inside a microwave oven which is designed to cause constructive interference at the centre of the oven, popcorn takes a long time (minutes) to start going. In the video, it only takes seconds at significantly decreased power.

Excuse me while I find these guys to ask them to stay off the internet. Anyone dumb enough to believe it, are gullible and should probably be removed from the breeding pool.... I hope one day someone invents the 'internet eugenics' program.....

That's definitely not an overreaction.

Could you care to explain to all of us what is special with 2.45GHz that makes it couple to water?

A microwave oven (I'm going to have to refer to a microwave oven and microwave(s) separately to avoid confusion) works by causing water molecules to align with the microwave passing through the food by the 'dipole effect' (water molecules are polar, the partial charge causes alignment, like small magnets in a larger field). Since a wave is AC, it flips back and forth, causing friction, and heat.

2.45 GHz is one of a few frequencies that on paper work, but its the only practical one for consumers. Specifically, 2.45 GHz is off limits for communications, and some of the other frequencies (one around 900 MHz, and some up around 5.8GHz, and 24Ghz) are impractical to fit into a consumer product because of the power required to make RF at that frequency and power. So technically 2.45 GHz isn't the only frequency that works, but its the most common, and even then if you look up cell phone frequencies you'll see theres a nice big gap on either side of 2.45 GHz. Even then, we've all seen how much power a microwave oven takes, and even by miracle of sketchy math the constructive interference wouldn't create near enough energy even if it was the right frequency.

I may have been a wee bit brash with my initial response, but I really do enjoy picking apart fake videos with a sadistic pleasure.

Now we know that you can copy from wikipedia. Now let us look at your claim:

around the 2GHz range, and even then, they do not emit the exact 2.45GHz required to couple with and heat the water inside the popcorn kernels.

Since the difference between 2.45 GHz and 2 GHz for the heating of water is insignificant, I can only come to the conclusion that you don't know what you are talking about and that your post reads remarkably like a suicide note.

I don't know a whole lot about this, but besides the phone isn't there radiation given off by the cell phone towers presumably at much higher power then the actual cellphones. None the less this still looks fake to me. Also, what about directed energy microwave guns.

I believe 2.45 GHz is a harmonic of the resonant frequency of water IIRC.

Does that mean you believe the video? Since your a mod, you win. I'm going on vacation so no point in turning this into a flamewar. My main miff with it was that the popcorn went straight up immediately, perpendicular to the table. I'm an organic chem student so I do have some background. What I'm not is a physicist, thus I do need to consult other sources from time to time.
