How to film the inside of a microwave (2 ways)

I'm going to show you two

ways

to

film

inside a

microwave

and along the way I'm going to show you the easiest way to make a plasma in a

microwave

, none of this cutting a grape in half or lighting a match right now. You are guaranteed plasma in a microwave every time. It all started with a WhatsApp conversation I had with my wife Leanne when she was out for the night and I was home alone at 10:33. I sent this message. I think I figured out how to

film

inside a microwave. I'm going to have a play.

She responded almost immediately saying exciting. She tries not to break the smiley face on the microwave. You might assume that message is passive-aggressive if you don't know Leanne, but it's not. she really supports me two minutes later at 10:35 i sent this message two minutes it was very sudden i thought i had figured out all the things that could go wrong but it turns out there were some unknown unknowns anyway she responded saying question mark solvable is a good question, right? We'll come back to that in a minute, but the reason I wanted to film inside a microwave and you'll know if you've seen previous videos of mine is that there are fun experiments you can do that involve putting something in a microwave.

The problem is that it is difficult to see the results of that experiment due to the structure of a microwave door. They are microp doors made of several layers, at least two layers. of glass that give you shine and reflection, but the most annoying thing is that you have this layer of metal mesh that, although it is annoying, is actually the most important part of the door from a security point of view because it is what prevents that microwave radiation comes out of it. the oven, so I thought if microwave radiation can't pass through a metal mesh, maybe I can put a camera in the microwave if I surround it with a metal mesh and you probably know this: you're not supposed to put metal in a microwave .

I mean, I questioned that, since the inside of a microwave is made of metal, so as a test, I just received a sheet of metal mesh, just a small square, and made it flush against the inside of the microwave, which It's made of In fact, I put it flush with the door, in fact, which is glass, not metal. Maybe I was wrong because one corner of the metal mesh heated up incredibly quickly and literally in two seconds I opened the door with a glowing red heart. and it melted the glass, there was a small blob of molten glass so my plan was to wait for it to cool and just remove it because I didn't want anyone to know.

I did it, it turns out that the glass inside a microwave is hardened and one of the side effects of hardening the glass is that if you introduce even a small crack it will spread very quickly to the rest of the glass which is what happened when I tried to touch it , so at least that's the question, but it got me thinking: why can't microwave radiation pass through those little holes in the metal mesh and it's actually a quirk of wave dynamics, so that microwaves are electromagnetic waves and waves cannot pass through a hole if the hole is substantially smaller than the wavelength of the wave, so microwaves have a wavelength of about 12 centimeters, those of A microwave oven has at least one and the holes in the metal mesh of a microwave door have a size of approximately one or two millimeters.

Why waves can't pass through small holes is a bit complicated. I don't think there is an intuitive way to explain it, but it is outside of mathematics, one of the results is that if you take the relationship between the wavelength of the wave and the size of the hole and then raise it to the fourth power you says how much the power drops the wavelength of microwaves is about 10 centimeters the holes in a microwave rack in the door about 1 millimeter, so it's a factor of a hundred difference, raise that to the fourth power, you have 8 zeros, so the amount of radiation outside the microwave is one 100 millionth of what it would be if the holes were about 10 centimeters wide.

How does that help us film the inside of the microwave and thus reduce the The power of the radiation by a factor of a hundred million is clearly Oh, a death, we could make the holes bigger Quick safety warning Modifying a microwave oven can make it dangerous This It is not for children, it is for adults only and if you are planning to modify a microwave oven please note that you must assess the risks yourself this video does not constitute a risk assessment let's assume the holes were one centimeter in size, that is a difference of a factor of 10 compared to a wavelength of 10 centimeters, so 10 to the power of 4 is 10,000, so if the holes were 1 centimeter in size, the microwave radiation would be attenuated by a factor of 10,000 compared to a hole that is 10 centimeters wide for me that's fine and it's also big enough to put a camera phone in front of it if you subscribe to In Kody's lab you will have seen a method similar to this, although he it comes from the side where the video is no longer available.

It's a long story as to why, but the short story is that Cody's Lab is an amazing channel and you should check it out. I actually skipped one step which is removing the layer of glass on the outside and the glass inside produces reflections, but actually something more interesting that I learned when I was analyzing the safety of all this is that although the mesh stops The microwaves that are They propagate outside the microwave actually attenuate over a short distance, so right next to the mesh there is some microwave radiation, but it falls off exponentially. I think that's why you have that layer of glass on the outside of the microwave which actually creates a space between you and the mesh, so as a note of caution, do not place any part of your body against the mesh when you are doing this experiment. , especially don't put your eyeball against the hole as it can cause cataracts anyway, that's how I was able to film such shiny CDs and glass melting, but it didn't work for 2 other videos I wanted to make to explain the second method to fill the inside the microwave.

Think about how a pinhole camera works to illuminate a scene. You want to take a photograph and the light bounces off objects in the scene towards the camera, but think about the direction the light needs to come in to enter the camera, so that the light coming out of the subject's foot can travel in one direction. to enter the camera, which is in this direction, like bouncing off the subject's head, there's only one direction it can travel to enter the camera, which is in this direction, so you get this inverted image inside the camera, here's one I made and it's abandoned I sail out of my studio and here it is, through the pinhole camera, there's al

ways

a compromise with a pinhole camera, which is that the hole is very small, so not much goes in light on the camera, the image is very dark, so what you do is make the hole bigger, but the problem with making the hole bigger now is that the light coming from your scene has a range of directions in which can travel to enter the camera, making the image blurry.

What is the solution? The solution is to use a lens if you stay. a lens into that larger hole on the pinhole camera then it will focus the light, it's no longer a pinhole camera because you put it on the lens, the lens probably focuses on objects at a specific distance, anything in front of that will be out of focus. Behind it will be out of focus and if you know a little bit about cameras you'll be familiar with this tradeoff, like if you want everything in your stitching to be roughly in focus, then what you want to do is on your camera. close the aperture, make it smaller so your camera looks more like a pinhole camera.

In fact, I can demonstrate it with this video at the moment when my aperture is wide open, so I have what is called a narrow depth of field, which means that there is only a kind of short range of distances that are in focus, which is around my face, everything in front is blurry, everything behind is below, like the war in the back, but I can control it from my phone, so if I close the aperture, there is less light. As you enter, it is getting dark. I'm going to compensate for that with the shutter speed so I can see the darker scenes, but the back wall is now more in focus and so is my focus this morning.

We use this to our advantage to shoot inside a If you have a DSLR with a really nice lens, like a prime lens, you probably have a very low f-stop, you can really open up the aperture, mine goes down to 1.4, which definitely It is enough to browse the interior. microwave and then focus your lens on the subject inside the microwave and the grill will be completely out of focus and act almost like an ND filter, as if it darkens the image, which you can then compensate for in other ways, this method is superior to the phone method with camera In some respects, if you're filming something that produces its own light source, such as a wolf, then you'll probably want to manually control things like the ISO f-stop shutter speed.

Things like that, which are often not possible with a smartphone, it's just a better picture. You also know that a DSLR with a good lens is a better image even through mesh than a camera phone. The other thing is you know you've drilled a hole. in your microwave, that's the only place you can film, that's the only camera angle you have, whereas with the external narrow depth of field method you can move the camera wherever you want, which brings me to the main event, how to make a plasma in a microwave guaranteed, so some methods involve cutting a grape in half and you have to leave a little skin on it, that works like 1 in 10 times, it's pretty unreliable, maybe I just don't do it very good, but anyway I discovered that if you buy carbon fiber fabric and tear it off a little bit, wrinkle it a little bit and put it in the microwave.

You will always get a plasma and all you have to do is place a Pyrex container on top and you can catch it.
