I thought I would be making massive arcs and plasma in my microwave oven putting all sort of metal and cutlery in it and maybe kill a few things. But alas!

Hi is it possible to put metal in a microwave oven? Let's put this spoon for 30 seconds and see what happens? Okay, it's a little bit hot, not too awful, though so i guess there has been some high amounts of current running through the metal to make it still touchably warm, so not a lot of power consumption. But now what? If i put two spoons side by side in there here, we go still nothing eh well, ouch. They are hot, but nothing terrible happened. I mean the food gets hot in there too.

So what's the big deal? Well, let's raise them a little bit on this empty cardboard box and see if that makes a difference, still nothing. I bet these are pretty hot. Now, oh, even the cardboard box is hot. Let's place them pretty close without touching ready, no problem, so i guess it's! Okay, to put metal in the microwave, no, we must be missing something i wasn't putting metal in the microwave supposed to be dangerous.

Let's put them in this glass at an angle, and maybe that makes a difference. No touching. There is only this much space between the spoons and there is still no arcing who said that it was dangerous to put them in there. So the question is under what condition it gets dangerous to put metal in the microwave.

I have seen these metal stands for microwave ovens that they put food over to warm it up. So i guess it is okay under some conditions to put metal in the microwave, but what, for example, it should be fine to place a flat piece of metal in the oven without a problem. See metal in general reflects most of the electromagnetic wave in there, but obviously it's getting warm so it must be absorbing some of it. Yeah it's a little warm, not too bad.

Actually i mean the body of the oven is made of metal. So it's all reflective and shouldn't be a problem, and i assume this also acts as a very good reflector. I wonder what happens if i place a spoon with a distance on top of this in the oven. Let's give it a try: let's bring the spoon even closer to the aluminum sheet.

Still no arcing, though, but i bet they're all getting warm. Oh yeah, they are pretty hot. Let's try again, i put the spoon directly on top of the aluminum foil. I bet nothing happens again.

It was supposed to be dangerous. I'm going to put these spoons vertical and parallel to each other. Like this in the oven, see what happens there we are. I was expecting some good arcing, nothing! Oh smoke! What's going on? Oh! No! No! No, it's gon na set my alarm, my clamp melted in there, so something is getting warm damn it well.

If i remember correctly, if you put two aluminum foils like this close to each other in the oven, it should arc. Well, let's see oh geez. Finally, there we are it melted, but apparently not because it arc to this one, because this one is not melted. So, what's going on, let's just put one of them in there and see what happens.

Why did this one melt then try again in a different location? Where is it arcing to? I think i see what might be going on. It's just jumping from the very sharp edges. Maybe that's why? Because these spoons don't have sharp edges, so nothing jumps out. Let me make a sharp tower and see what happens.

Sharpie sharp. Let's do it! Oh yes, yes see, the sharp tip is gone, so is it just dangerous to put sharp metal in the microwave and every other round? Soft edge metal in microwave oven is fine. Something important i should mention: if you put a fork in the oven. Well, nothing happens what any kind of metal you put in the oven that touches the wall of the oven.

That will happen, which is bad. I don't know why. I thought the arc would jump between two pieces of metal, but apparently not so arc just happens with a piece of metal with sharp edges. Not even this, let's make it wider a little bit.

Does it have anything to do with the length of the piece? Maybe oh, this is long i'll, just lay it flat and see they just get warm. Oh geez. What happened it arced right in the middle of it. What if i cut it exactly at 12.2, millimeter of the wavelength size should be the best antenna to pick up that frequency.

So far the edge was the king. Well, let's raise it a little bit higher. I want to put it in the middle of all the standing waves, how about half a wavelength? Nothing! My box is super hot, but nothing else. Okay, so based on all my tests, it's just the sharpest edge that the ark might jump off of.

So let me try my exacto knife i'll erase it on the box too. A little bit see what happens, not even the sharp edge of the knife. Is it safe to put metal in the microwave, the hell man, let's just drop it on the bed. What a artless piece of video this is! This knife has a ton of sharp edges.

Okay, i take the glass out. I just put a piece of plastic in there and a spoon on top spoon has round edges, though so no rotating spoon anymore. How about a half a sheet on the plastic? I want the knife, nothing! I just have a hot crispy knife, so it's all just about very sharp edges of aluminum foil. What, if i make a ball? My power level is at maximum, so there is no excuse for not arcing how about a loose ball.

Oh, i saw some ark now the bed might work because it might move the ball into a much more powerful area of the chamber. It might be just unlucky and put the ball in a low power area of a chamber in the low power standing wave side. I did show in one of my old videos that hitting a box you can see hot spots of the microwave standing waves and rotating the box with the plate, helps heat up the box more evenly, and so it's more likely for the metal to go over high Energy spots here, just put it in there: oh arcs, nothing magnificent. I remember the first time i saw an ark was when i put two sheets of aluminum foil side by side and they were in zigzag, shape, something like this, and i thought they were jumping to each other.

Let's try it! Here's my foils. I heard something: oh there you go, this one has the bottom of it melted and the other one has the top of it. Melted, so they're not jumping to each other they're. Just jumping, let's put a single one in then there you go so arcing in the microwave, which is not a healthy thing to happen in a microwave, because arcs generate or consume a lot of energy and can fry your microwave only happens when you have very sharp Pointy edges of aluminum foil in your oven and when the table turns and the foil goes over an area of high concentrated energy, it could arc there.

You go stop it. So let's try one last time to confirm my theory. I made a piece of sheet, mostly with round edges and only one spike at the top. If it jumps only from the tip there, then my theory is correct.

Okay, what happened? Well, the tip is gone, but the side is completely gone too. I guess the entire edge of the foil is sharp anyway. Well, let's put an empty can of soda in there and see what happens? Nothing and it's a little bit warm. So the moral of the story is, it seems if you accidentally leave metals in your microwave oven as long as they don't have very sharp edges, there shouldn't be any arcing and they just warm up like food.

I suppose, if you leave them in there for extended period of time, the metal can get super hot and dangerous, but other than that, it's very hard to make an ark in a microwave oven. I mean it's easy if you know how to make it, you just need a ton of sharp edges, let's put all of them in there and turn it on. You should be getting arcs anyway. There you go wow nice, stop it and that if you leave it in there for a long period of time could put too much load on your oven and burn it.

But beside that, if random cutlery are in your oven, probably nothing happens. Just be careful. Okay, i've never been so disappointed in the lack of arcs pay.

    you need have everything ready on microwave, so just shut door and hit start button. then use what ever available to hold wooden tooth pick. stab tpick into whatever you have for base so its standing up lime a tiny little flag pole , set into microwave, light top end if tpick , after about 1/4 inch or so burning. now quickly blow out fire, slam door shut and start. carbon smoke particles will cause a plasma arc……soooooo cooool. oh simply shut off or open door to stop reaction🙃

    Modern microwaves must be built different. Back in the early 2000s I left a fork in my bowl of porridge and it looked like war of the worlds inside 😂 had to get the card filter thing replaced because it'd just spew out plasma everytime you turned it on.

    Try cooking electronic components in a microwave! Try TTL chips, transistors, CAPACITORS! I hate TTL – they should get top priority to go in the ovens! 😁 Everyone, please microwave all of your TTL chips.

    I've had a can of soup throw arcs and melt the plastic gear under the glass that turns it. I don't know if the can was aluminum or tin, probablu aluminum but the arc was from the bottom. This was years ago so I would think more modern microwave would work differently

  5. Avataaar/Circle Created with python_avatars jerard208 says:

    maybe it has something to do with the "inverter microwave technology"? inverter microwaves are more sophisticated and have more security features, what if you try it with a more old-school transformer microwave? might be more arcs.

    In my microwave instruction manual they recommend putting a teaspoon when heating a cup of water because else the water might get superheated and spontaneously boil when you put something in it.

  7. Avataaar/Circle Created with python_avatars StarkRG says:

    Wouldn't the low resistance of the metal create a higher than normal current in the magnetron, even without creating arcs? A few seconds might not be an issue, but if, for example, you're trying to defrost something you've frozen with a spoon in it, that might be in there for a few minutes. Of course that spoon is going to heat up a lot faster than the frozen thing so you'd be able to pull it out long before the whole thing was defrosted.

    I also Accidentally Researched😅 on this and found out
    You you put Biscuits which have Aluminum packaging into the Oven sparks will be Generated…

  9. Avataaar/Circle Created with python_avatars Atash Gallagher says:

    My question is how the hell does arcing in the microwave oven cause increased load?

    There's just power going to it creating the microwaves. Isn't that like blowing out a lightbulb by putting to much black paint in a room?

    Thanks for jumping on the AmpHour! I enjoyed hearing your discussion with Dave about the many things you guys talked about! You've made a difference in many lives by helping to understand things in "just the right way"!

    Probably somebody has already mentioned it. but older ovens created funny things with forks inside, it was a really scary storm of arcs, but it had no issues popcorn bags that have a metal sheet on the bottom side. Now my microwave oven is rated for 1100W output power (this is actually the most powerful microwave oven I have ever seen) it has just a relay to power up the HV transformer but has never had issues with metals inside.

    You missed one thing, you are puting aliminium and stainless steel that are not magnectical and if you see that piano steel of that spring was burning hot and melted the clamp. Try a regular steel and see the diference

  13. Avataaar/Circle Created with python_avatars Leonardo Sestari says:

    Maybe what makes the arcs is when the metal gets too hot and vaporizes. That would explain why only thin pieces of metal (like the aluminum foil) create an arc, since its easier to heat up smaller masses. If this theory is correct, leaving any piece of metal in the microwave would arc, if left for long enough time in there. Might make for a good follow up video…

    Thanks to Ali Humaydan for bringing the idea to my attention! One more item off my list, and I didn't kill the microwave oven in the process either! Nguyen – Nguyen! (look up the pronunciation)
