you don't need expensive carbon fibre tissue... with a match and some fibre of iron wool to self ignite the matches head in the closed running microwave, this will light the match and than the flame will boost to a bigger plasma cuz flames are plasma too... you will get a dense plasme ball, don't use a beaker, uae some thing like the beaker but with thiker walls because otherwise it will melt thruogh the beaker and the microwave ofen should be a robust one, because the dense plasmaball will over load it substantially

A note about using mesh screen vs. a perforated metal sheet as an attenuator: The woven nature of wire mesh results in what is effectively, a tiny resistor at each intersection of the wire mesh due to very small contact areas, and oxides on the surface of the wires. This results in ohmic heating and thus the hot spot as noted. Perforated metal doesn't have this problem.

Sir, you have more than 1M subscribers. You have decent income to buy microwaves everyday. How did you end up with a nasty piece of work (your wife) that dares to blame you over a cheap microwave? Is she a billionare? Or are you allowing her to abuse you because of sexist (antimen) laws regarding mariagee. Check out An Ear For Men channel. I would save you (not her) if we run into the aftermath of World War III. You will save modern science. She can blame Men and have bedtime with you once in a while. She Just doesn't worth you. She should be modest and loving. Not bitching over a cheap microwave.

thanks for the awesome explanation of aperture! I knew what it was used for, but now I know why it works and will be able to remember it a lot better.

I super appreciate that you show things going wrong / breaking, as well as it working! It's affirming and informative to know that stuff breaks when you make and record these cool phenomena. :)

Stumbled upon your channel. Glad I found it. You’re a good teacher. Your method is very fluid. Good job. Subscribed.

I love the pinhole camera, in my room in the morning I can see outside without opening my curtains, theyre sun blocking (makes your room dark) so it basically mimics the box and pinhole idea

your explanation of a camera obscura is perfect! it's a strange concept to try to put into words.

dude I love your videos, keep on

I'm a prototype engineer/machinist for the Uni of Sydney and made a solution for this problem for one of the researchers. Basically we used a tuned length and diameter tube port into the microwave that allows physical access in and out while it's running while attenuating all the microwaves :)

This was really amazing!!

There is a math trick worth trying to get better pictures through the mesh : fast Fourier transformations. I used the field of view/aperture trick a lot for taking pictures of animals thought a wire mesh in zoo, and although those mesh are a lot bigger you can have decent results. Seems like a DSLR with a wide aperture performs good enough for HD videos, but there might be a way get good results with less performant hardware. Recently while scanning a lot of old family photography, some of them where on a textured paper and needed to find a way to get rid of that pattern. That's when I discovered the marvels of fast Fourier transformations. I wonder how an FFT filter could improve a picture/film made through a mesh, but I believe it could be incredible.

Steve this could not have been timed better. You uploaded this while we were watching the recording of you doing this live for FOTSN...!

Metal is fine in the microwave. It’s not about metal, it’s about heat dissipation. If you put tin foil or a metal can in the microwave heat will build up in spots on the metal, make plasma, then arc. This is because of how thin the metal is and how quickly heat builds up in spots. If you leave a thicker, rolled steel fork in your food no problem (not cast iron too many holes and voids). No it will not break your microwave. The magnetron puts a fixed amount of energy into the faraday cage. If that energy is absorbed better by a piece of metal the magnetron doesn’t get hotter it’s output stays the same. Only 2 things will break your microwave. 1 putting something in the faraday cage that heats up to the point that it melts or breaks the faraday cage. 2 running the microwave empty, this causes all energy to build until the microwaves find imperfections in the faraday cage to escape through damaging the faraday cage. The safety mechanisms in the microwave prevent it from running if the latches or faraday cage are broken, therefore broken microwave.

The trick with very open aperture and the micro oven grill at 8:50 is very useful at Zoos. Very bright full frame telephoto lenses, more than 85 mm with large aperture, larger than f/2.8 can disappear the cages. The longer focal length and bigger aperture deliver better results. It is a trick of optics.

excellent work young man.

I seem to remember when you first filmed something in a microwave and wouldn't say how you did it, then Cody showed how it worked. I mean, nothing against you, I like your content, but I gotta have the most respect for Cody because he basically shows us everything always.

"The reason waves cant fit through small holes is kind of tricky, i don't think there's an intuitive way it explain it" Here's one: If they're too big, they don't fit.

thumbs up for slow mo guys research

This video, revisiting it, gave me an interesting viola moment of how evanescent waves are related to diffraction which means how boundary conditions of Maxwell's equations are related to diffraction. Evanescent waves are the limit of the number of slits going to infinity and the size going to zero which is similar to the infinite series to represent a decaying exponential.

Being so nice to Cody after he threw that shade at you in the original video. Peace on earth and goodwill toward men.

3:00 min into the video and... voilà!!! Magical hair cut happens!

Just doing some rough calculations. Microwave ovens output between 600 W and ~1500 W depending on model. Radio frequency exposure limits vary around the world as to power density in millwatts per centimeter squared mW/cm^2 and as to exposure time. In the US, the general population limit is 1 mW/cm^2 averaged over a 30 minute period. So, let's say you have a 1000 W oven. Converting 1000 W to mW gives you 1,000,000 mW. Assuming you have all the 1000 W of energy is bouncing around the inside of the oven and is available at the enlarged hole in the mesh for the camera (it's probably not, but figuring worst case), you would need to attenuate the RF energy by 1,000,000 times to reduce the 1,000,000 mW down to 1 mW. That is a factor of 10 to the 6th power or an attenuation of 60 dB. That is a factor of 100 more than the 10 to the 4th power you've estimated. Since the hole is 1 cm in diameter, the area is 0.785 cm and the power density at the hole would be 1,000,000 mW x 10^-4 / 0.785 cm^2 = 127.3 mW/cm^2 using your estimate of a factor of 10 to the 4th power reduction from the 1 cm diameter hole. As stated, the power levels drop off exponentially with distance from the hole and there is a time averaging function over the 30 minutes so if one is only running the microwave oven for a few seconds here and there over the 30 minute period, that helps. All that said, would I try this if I had a spare microwave to play with, probably. But I'm a EE who works with radio waves and who has a spectrum analyzer and other test equipment to perform RF measurements to verify everything is safe. For the average person, as they say, your mileage may vary . . .

Amazing how much he changes looks during each cut

Not that I’m ever going to do this it was cool to hear the explanation

I believe that the heating happens on corners and edges, where there is an abrupt change, and a cavity or resonance set up, plus the entire metal is acting like an antenna, and all the energy it picks up tries to concentrate on the small places and reradiate. Where the corner of your screen melted into the glass, you were likely actually creating a resonant chamber between your mesh and the mesh in the door, and it was concentrating energy there. Also notice how the door mesh, vent mesh and interior light mesh also all use round holes rather than slots anything. I wouldn't be surprised if this reduces the heating of the metal. I suspect that if you took your screen, preformed it over a ball or something on the table to get smooth curves tapered into flat edges to blend in, and then taped it to the flat end wall so that the edges were in contact with and blended smoothly into the wall, and everything was smooth, that it would heat much less. If you wanted to put a camera inside, you would probably need to basically actually make a new end wall matching the edge radii, so that you didn't get any blind corners or loose edges. The problem would be that the inner glass would prevent you from sealing it to the door mesh, so you would have a lot of energy get behind the wall to the camera, and probably melt the edge. Since you already have a busted microwave, you might be able to replace the punched round hole screen with the fiber screen to get more light through and better images, or just cut a section out and attach the screen over it. You might still run into problems with edges, or with the "sharpness" of the square woven mesh itself. If you cut the mesh large enough to get pinched between the door gasket and the face of the door frame you would be able to eliminate the most edges to heat up. If the square mesh heats up, you could also take some thin sheet metal and drill a pattern of larger holes in it, possibly even with tiny holes in the diamonds between the larger holes to get as much light as possible. That sounds like a job for someone with a laser cutter, or cnc machines, maybe another collaboration? Lol You could also buy pre punched sheet from suppliers like Mcnichols.com Imagine replacing the front, top, and end with mesh and being able to get multiple angles and good lighting!

So a microwave can melt glass in 2 second but my hot pocket is still cold after 2 minutes

Amazing videography technique @2:58 : "The Haircut Cut"

I guess I see why the KZread algorithm recommended Nile Red to me now. I watched half of this video, then had to leave home and didn’t finish it. The next day, I saw a video by Nile Red on the home tab in the KZread app that looked interesting so I watched it and really liked his channel. Then I came back to finish this and for a second, I thought it was a huge coincidence, but then I realized that KZread probably noticed a high correlation between watching this video and watching his channel. Kind of interesting.
