Fun fact: Faraday called this em sieve and his mom was angry once just before the lunch time. That does it - she said. No more school for you! - she added.
That's a good video, but my praise stops there. I just tried this with a metal splatter guard and sieve as you've used, with an FM radio. It had no effect on reception whatsoever!
Thank you for the video. Quick simple and to the point... I absolutely love videos like this! It is always interesting when you view the comment section of older videos. The seemingly sporadic timeline that comments tend to follow. It's even more interesting when the video doesn't have a lot of comments... 8 years ago 5 years ago 7 months ago 2 weeks ago Well I'm rambling. Like I said I enjoyed the video thank you very much! As a side note: I'm not blowing smoke, this video deserves a lot more comments and a lot more viewers than it has!
@Sussy ass motherfucka yyyyyyea no. If the gaps in a Faraday cage are a minuscule fraction of the wavelength in question then the waves are not getting through. end of. There's a reason microwave oven doors have a thousand tiny holes in them and no microwave radiation escapes through them.
All the faraday cage does is absorb/deflect the signal and direct it around the object inside it. The emi/emp will not pass through the faraday cage. Fire on a gas burner will do the same, hold a steel screen above a gas flame and lower it down on the flame and the flame will not pass through it. Grounding the faraday cage will just give a path for the electric potential to disburse to ground instead of holding a charge on the faraday cage. There is a fine line between a faraday cage and a signal antenna, so be certain you fully understand how a faraday cage works.
Indeed. You can see my demo uses a transistor radio instead of a cell phone. That was entirely deliberate and intentional. A tape recorder playing a cassette is unaffected by being encased in a Faraday cage. Your phone is similarly unaffected while playing music in a Faraday cage. If the music is a file on the phone’s memory chip, it does not rely on the reception of radio waves broadcast from a distant transmitter. Even if you use a radio app, there will be varying degrees of buffering. I used a transistor radio because there is no buffering and the music is a fairly instantaneous amplification (and transduction) of a radio wave signal. Once that external signal is lost, so is the music. Did you try calling your encased cell phone?
We are-all of us-entitled to our feelings. But don’t let your feelings stand in the way of science. In science, we avail ourselves of the opportunity to replicate! The materials are not terribly exotic: a metal strainer/colander, a metal splatter screen, a transistor radio small enough to fit in said colander, and a place in which AM and FM signals can be received. Try it yourself, and your feelings will subside.
@@Jon-O. Fried? Fried by what? Remember that neither radio reception nor Faraday cages are cutting-edge exotic technologies anymore. What’s at question is the difference in behavior between AM and FM signals relative to said Faraday cage.
@@Jon-O. Under such circumstances, the details of this demonstration will be among the least of anyone’s concerns. Nor will a ground wire insure complete safety.
Wow! I've been to Brazil many, many times (mostly to Minas Gerais) but haven't gotten to the Pantanal yet. Very cool videos! "Parabéns pelos vídeos" :-)

I liked your video and you didn't even say a word. You did have to...so a faraday cage to be effective needs to not just be a cage over you or the device but under/ completely encompass...did you learn this on your own or is there a good source you learned from? Most of these videos on the faraday are repeat pedestrian garbage
cost more will never do, however ZTE has abandoned the V8 Pro and has said that he has no plans to update Nougat, much less Oreo, it's a shame that they let a
