Cell Phone Popcorn Trick Revealed

By July 9, 2008

Follow me on:

Screenshot of YouTube video: Cell phone popcornYou knew it was a hoax, but were you able to figure out how it was done? One theory held that there must have been a heating element under the table. Another posited a hidden microwave transmitter. Yet another concluded it could only have been done with special effects. Now, for the first time, Cardo Systems CEO Abraham Glezerman reveals how the illusion of cell phone popcorn was created for the viral videos that took the Internet by storm.

I tried this w/3 cellphones and it actually made the popcorn hot, so it’s not a hoax!

Hey stupid it’s …

“you’re stupid”

as in the contraction of “you are” and not “your” which has a different meaning.

Were you not listening in the 3rd grade?

(7) Stephenie LaMaina says:

My son, 10 years old, and I tried it with one cell phone and it did not work. While waiting for the rest of our family to be at home (to try it with three cell phones) we talking about. Since it takes about t 2 minutes to pop a bag of popcorn we wondered how long it would take to do 4 pieces. The first 2 poped at about 1:33, the third at about 1:46, and the fourth still had not poped after 2 minutes. Since cell phone don’t ring for that long we figured it had to be a hoax.

(8) Mr.M says:

that’s right! Moreover, a microwave oven output power is about 600W (enclusured in its cavity), while cell phones delivers less than 1W (disperse in the air).

We can only hope your head pops when you use your phone as well. That would be good for the gene pool.

(10) Jim in Hartford says:

You gotta love how the CEO stands there and lies about never intending the video to foster a fear of holding cell phones next to your head. He says it was made to be funny. His company makes blue-tooth headsets! They’re hoping that a fear of holding the phone to your ear will make you look into buying an earpiece! What a bald-face liar!

Jane, James Jones is wrong, you’re not stupid … you’re an idiot.

James Jones, you’re stupid!

I believe the term for Jane is ignorant fabricator – Ignorant in that she doesn’t understand scientifically that none of what is described can happen, fabricator in that she shamelessly admits witnessing this…ah, throw in idiot for not understanding that most people with common sense don’t believe this anyways, and will view her as an ignorant fabricator ;-)

(19) Rastus says:

amazing how many really clever people have read this – I have a new Nokia phone and after 5 minutes talking the thing get’s damn hot. Gotta be a reason – heat means energy and now with 3G pumping massive bandwidth I tried the popcorn trick as well. So I am stupid as well (or an idiot depending on your definition). But I feel less stupid finding out it was a hoax than all you clever people who just knew that it would never work. Who knew that your mobile phones are safe, or the telecomms industry/govt would intervene. Just like tobacco isn’t harmfull or addictive ;-) I’ll happily continue with being stupid in your definition.

(20) Rocket Scientist says:

A microwave outputs 600 to 1000 watts of energy into a closed cavity at a frequency that causes the water molecules (also fat and sugar) in food to vibrate and heat up.

Cell phones have a maximum of 0.3 watts and are on the wrong frequency to vibrate dipole molecules and the antennas are designed to spread the signal in all directions.

Of course it doesn’t work.

You are really a rocket scientist …are n’t you ? at least you talk like one …. But the rocket only takes off after you smoke few joints….

(22) Dave says:

Larry King did a show on the potential link between cell phones and brain cancer (http://www.youtube.com/watch?v=XVtTnKIwXu4). Credible doctors acknowledge a possible correlation, and Johnnie Cochran’s widow believes his excessive cell phone use caused his fatal brain cancer. Are cell phone users safe? The jury is still out.

October 24, 2008 at 10:45 am
(23) Hank6 says:

Oh, whatever Rocket Scientist! Right in the middle of all of these kids questioning each others intelligence, you had to explain it scientifically?

I rarely use my cell phone but I do try to keep it away from my crotch when not in use. The phone. Not my crotch. And I never did believe the video in the first place. I’m too smert to fall for that! ;-)

October 27, 2008 at 1:09 pm
(24) Jan Steinman says:

Rocket Scientist says: “Cell phones have a maximum of 0.3 watts and are on the wrong frequency to vibrate dipole molecules and the antennas are designed to spread the signal in all directions.”

Almost right. Cell phones have adaptive power settings, and can actually pump out several watts in weak signal areas. And while it is true that microwave ovens are optimized for the ~2.4GHz frequency at which water molecules vibrate, many early microwaves operated at 900MHz, only slightly above the frequency that cell phones use — it’s just somewhat less efficient.

But it is certainly true that cell phone antennas are “omnidirectional,” and do not provide a focused beam of energy.

Sorry for the nit-picking. But since we’re getting technical, might as well be accurate. (I was a radio frequency electrical engineer, and have had an amateur radio license for nearly 40 years.)

To, ‘Jim in Hartford’, Lighten up Buckie! We get lied to worse than this in any single hour of prime time Television. The mindset of our society is seemingly bent on adopting a hawkish, take no prisoner, confrontational mentality. Can’t find it in my heart to condemn a man trying to market his product. At least he made it interesting.

Marketing has changed radically since the days when subliminal seducers sniped at us from Madison Avenue art work in the ’60′s. Now anyone with a decent processor, a $300 video card and trial version software can do the same without oversight or scrutiny. There’s online tutorials covering upper level skills that’ll let ya render like the big boys.

(43) lizzie says:

Cell phones may or may not pop corn but the surely DO emit dangerous radiation. Just today I had a lady who lost her son to cancer. He worked long hours with a cell phone headset in his ear and the cancer was concentrated in that same ear. Coincidence? Perhaps, but I’m not taking any chances. She’s convinced based on doctors reports and is telling everybody she sees wearing a headset about it. Sad story.

Non-believers beware. We had two mobile phones sitting on a table together and they rang at the same time by chance and nuked our unsuspecting cat that was walking by… well ok scared the crap out of him…

Hey, I had a great laugh reading all these comments. I’m a teacher and I intend to use the video and the comments about it to teach my students how to “question everything” they see on the internet. I figured it wouldn’t work but wanted my students try it for themselves. Thanks for the great scientific explanations and information.

June 12, 2009 at 3:42 am
(46) OutOfTheBlue says:

I am not surprised about the possible repercussions of using a mobile phone on a continuous basis. Yes it was a hoax but why have serveral authorities including the French, Canadian , Russian banned mobile phone use to under 16′s and why do mobile phone providers have to publish SAR ratios if their is no health concern.

Then we can start on Mobile phone masts…

comment 30 by psych-girl, love it. Use focus group discussions to have kernels internalize their feelings of inadequacy and anomie, then channel that towards a desire to burst forth in a massive trans-substantiation. They will pop! No need for weed.

(50) willer says:

Rocket Scientist is right, why it is hot? of course same reason as why your digital camera batteries is hot after continue using it for hours? cell phone magnetic wave is enough to light on the LED that requires 8-25mA, but not enough to heat the popcorn and make it pop.

September 13, 2009 at 11:30 pm
(51) blah blah blah says:

erm… the reason for cell phones (as well as any other portable electronic device from a few years back) getting hot after continuous usage is low efficiency of the previous generation batteries (NiMH technology had its efficiency around 50%). That heating has almost nothing to do with the radio waves. It is just the energy lost as heat when the battery uses its stored energy!!

October 3, 2009 at 12:09 pm
(52) Maurice says:

You know, someone sent me the cell phone/popcorn video. I watched about half of it and started having doubts. First, it seemed like there were a collection of these videos put together, ironically with the same quality of video in each but different ethnicities in the groups. That was the first flag. Then the fact that it takes at least 2 minutes to pop popcorn in a microwave but seconds from 4 cell phones…just silly. So I immediately did research online through a simple search to see if there was a hoax to it, or better yet, to confirm my suspicions and there it was. Funny that something like this would spawn anything more than a chuckle and maybe some simple research to see how they did it. And a Bluetooth headset company investing in the video – how absolutely gullible could these companies believe all of us are? Maybe I’m giving “Us” too much credit, but I would think this would be more of a marketing backfire than anything when found out. I guess they figure it’s better to bet on ignorance than insight…

(55) Concerned Person says:

We all know that cell phones run on microwaves. And we all believe (notice that i didn’t say know) that microwave ovens don’t leak radiation (in the form of microwaves).

If a microwave oven doesn’t allow radiation to escape (or leak radiation), then a cell phone signal shouldn’t make a cell phone ring if you put it inside of a microwave oven.

Unfortunately a cell phone does ring inside of a microwave oven. With that said, the real concern should be how much microwave radiation is your microwave oven sending throughout your house.

Funny you can always tell which sites and which comments come from folks that are get paid to post or who like to run to the defense of mega billion dollar corporations at the expense of public health issues. Call Microsoft, they’re always hiring and could use a few unsuspecting mouthpieces that just need a quarter popped into the back of their heads. Oops, I said the “popped” word…

Any other topic would have had a mediocre responses and mostly one sided as to public health concerns, but this time they came out in full force. It’s the hit dogs that howl!

I have enjoyed the funny comments. Thanks for the chuckles.
However, cell phones don’t use microwave signals. They are on a lower frequency than microwave signals. Microwave signals do not go through the glass as they are a larger wavelength than the holes in the shield in the glass. Cell phone signals are a different wavelength and can go through the holes. I can’t verify the effectiveness of the seal on your microwave’s door though, so you could have some leakage there. Do some research and you will see. I tried to state it very elementary as to not get too nerdy in my answer, so no need to trash me for how I said it. I don’t care.

(72) Mrs. anomanous says:

IT WORKS!!! 4 all u geeks out there who think it doesnt work…. I HAVE PROOF! i was with my friends cuz im doing this as a science project…. and we had 4 cell phones- 4 pieces of popcorn. three popped because:
there is a radiation wave that flows and creates a current and that radiation goes through as ultraviolet heat which will slowly cook the popcorn causing it to ”pop”. If u have about 5 cell phones and 5 kernels, one is bound to pop.
Because the small amount of microwave radiation that is given off by the phones when a minimum of 4 phones are placed around the popcorn there is enough microwave radiation to amount to that of a microwave oven.

August 7, 2012 at 11:27 pm
(73) Slawek says:

all cell phones suppose to meet important requirement called SAR – Specific Absorption Rate. why? to know, that they will not harm your body. cell phones does not radiate only through their antennas, which were visible in old days. in nineties cases of brain tumor from extensive usage of cell phone were reported. cell phone cooks but in much slower rate than microwave oven… in all experiments with eggs and corn one important factor was missing: what was the power setting of the phones!!! power varies with the distance to the cell tower…
