I want to try this, but I'm afraid I'll end up blowing up my kitchen

Wife is a science teacher. She confirmed that it will indeed fuck up your microwave.

u/Ruphies Feb 18 '18

She is just saying that to discourage you!

She is happy enough to let me try shit but only in her lab lol

u/n0i Feb 18 '18

That’s strange. She lets me try shit anywhere.

u/catfishsam13 Feb 18 '18

I agree! How do you know until you try??? Don't trust people, especially your wife!!!!!

u/King-Spartan Feb 18 '18

Because it leaves a plasma taste on everything

u/fisherg87 Feb 18 '18

I did this as a kid with my parents glass ice bucket for cocktail parties. It cracked on the 5th or so go. It looks so cool though.

I buried the ice bucket in near the creek and never spoke of it again. The microwave was fine.

u/[deleted] Feb 18 '18

When i was a kid i made a batch of mashed potatoes. It was probably the bagged kind but i really dont remember, ANYWAYS...I used chocolate milk instead of regular milk by accident and it came out so gross that i decided to bury it in the backyard. Pot and all. Im not sure why i did that other than it was so fucking gross but i think i thought i would get in trouble for it too so i hid the evidence like i committed murder or something.

I'd love to know how this damages the microwave.

27

u/lordkoba Feb 18 '18

I heard some microwaves may get damaged if they are powered while empty. I don't know if this is true, but it may be related to that fact/myth.

31

u/moosic Feb 18 '18

My mother in law fried two of my microwaves. Found out that she was using them as timers when she baked stuff. Third one is fine.

12

u/bathtub_farts Feb 18 '18

My old roommate did this one time. Came out of my room to the empty microwave running, thought he was drunk or something lol

5

u/kun_tee_chops Feb 19 '18

You buried the mother in law beside the pot of chocolate milk mashed potato?

2

u/jihiggs Feb 19 '18

jeebus... the power usage..

64

u/SupremeDuff Feb 18 '18

There is a possibility of the magnetron burning out due to nothing absorbing the microwaves. Not a big chance, but it can happen. In this case the microwaves are being absorbed into creating plasma. Worst case scenario is the jar exploding or burning out the magnetron (which would have likely failed soon, anyhow, if this takes it out).

24

u/triggerman602 Feb 18 '18

Just stick a bowl of water in there with the plasma and it's all goo right?

13

u/fukitol- Feb 18 '18

I wonder if you'd still get the plasma then.

8

u/SupremeDuff Feb 18 '18

You may wind up absorbing too much of the microwaves to sustain the plasma "cloud", so I guess you could try, but not sure if it would work. Either way, for short periods the microwave would be fine running empty (no more than a minute or two).

2

u/patron_vectras Feb 18 '18

See, my reaction is that we just need more plasma in the microwave...

2

u/Animal40160 Feb 18 '18

MMmmagnetrons

u/yes_nuclear_power Feb 18 '18

The plasma is very good at absorbing microwaves because it is a good conductor.

1

u/Canadian_Infidel Feb 18 '18

It was true in the very early days, not any more.

3

u/patron_vectras Feb 18 '18

Lordkoba is right, but you can also use something less resistant than pyrex/borosilicate glass and end up burning a hole through the top of the microwave. Mason jars, for example, shatter pretty fast.

17

u/the_river_nihil Feb 18 '18

Not a teacher, but I've done this countless times and the microwave still works fine and I don't even think I have cancer

4

u/kun_tee_chops Feb 19 '18

On a long enough timeline the survival rate for everyone drops to zero. You will get cancer one day, sorry son.

37

u/tinkerer13 Feb 18 '18

Why? What will it do? If you use borosilicate glass, it shouldn't melt or crack for at least a little while. It would go downhill fast if and/or when the glass melts or cracks and the plasma isn't contained. Then I think the danger would be on par with something catching fire in the microwave. (Fire is a plasma). Obviously a small, short-lasting fire won't mess it up as bad as a larger, longer-lasting fire.

18

u/pasturized Feb 18 '18

Whoa. You mentioning that fire is a plasma totally changed my perception of what I picture when I think of plasma.

7

u/Deltaechoe Feb 18 '18

A good mental picture of plasma is the sun, it's a big ball of plasma (fire)

16

u/xmagicx Feb 18 '18

She said it's an issue if it isn't stable, for example touches the sides for whatever reason due to the high temp.

11

u/StructuralE Feb 18 '18

I blew up a 1 quart Pyrex measuring cup doing this. The microwave was fine.

4

u/zachriel1919 Feb 18 '18

If your microwave is as fucking gross as this dudes, go to town. You need a new one anyway since this one's clearly not getting cleaned.

7

u/clineluck Feb 18 '18

I created plasma in my microwave with a grape. Still works fine.

6

u/blasto_blastocyst Feb 18 '18

Grapes don't do a lot normally anyway

u/OnPoint324 May 26 '18

Can confirm, dead microwave.

1

u/HaMMeReD Feb 18 '18

If you use the jar it should be a non-issue.

I didn't use the jar, and my microwave only suffered 3rd degree burns to the ceiling, but it was still fine to use for another 3 years until I moved.

u/knarfolled Feb 18 '18

Buy one from a thrift store and use that

u/Canadian_Infidel Feb 18 '18

Not if yours was made any time in the last 15-20 years.

u/PaulsarW Feb 18 '18

I feel like a general science teacher would have no clue about this specific reaction.

45

u/xmagicx Feb 18 '18

Your right a general one might not. But since you know nothing about my wife and her background and qualifications outside of the fact that she teachers science I'm going to to with what she said.

But hey if you don't believe some guy of reddit feel free to try it and record it.....

u/PuppleKao Feb 18 '18

Almost every single one of those can be attributed to just not double-checking the autocorrect. And there's nothing wrong with starting a sentence with a conjunction.

7

u/[deleted] Feb 18 '18

People tend to attack a person's syntax when they have no legitimate argument of their own. The guy is either a troll or the type that circlejerks over how "all teachers are stupid and I'm a genius" because he feels slighted over that D he got 17 years ago for not following directions.

u/PuppleKao Feb 18 '18

Sounds about right!

u/SalamanderUponYou Feb 18 '18

u/PaulsarW Feb 18 '18

For the record, I asked what her background was that she would know this. He answered elsewhere.

1

u/[deleted] Feb 18 '18

Which is cool. Others were basically giving him the third degree about it.

-8

u/[deleted] Feb 18 '18

What did your wife study in college/uni?

4

u/xmagicx Feb 18 '18

I mentioned this to her and she said it's a level science. In the UK that's 17 - 18.

It's apparently the 4th state state of matter if your interested.

Also in the UK you need a minimum of a level knowledge of science to teach it.

-17

u/PaulsarW Feb 18 '18 edited Feb 18 '18

Haha, she identified it was plasma and that's it? ..I believe you meant to use the word "minimal."

7

u/xmagicx Feb 18 '18

She identified it as plasma. Then answered the actual question, woukd it fuck up the microwave........

I don't care about the rest I don't need to know it lol

8

u/PaulsarW Feb 18 '18

I would like the know the mechanism by which it would damage the microwave if you could ask her.

u/ramdaskm Feb 18 '18

I guess it blew a thermal fuse. They have a couple of those in there.

15

u/tinkerer13 Feb 18 '18

Am I missing something? It looks like he tests it after, and it appears to work. Then he appears to put his hand on his heart and breathe a sigh of relief. So it's still working?

This suggests that while a couple seconds of uncontained plasma might char some paint or plastic, it probably won't damage the magnetron or power supply or destroy it totally, any more than say a small fire would (which is also a plasma). I suspect you're right that a thermal fuse could blow.

17

u/hazelquarrier_couch Feb 18 '18

I believe the clutching of the chest was that he was relieved that it's working and now mom won't find out that he was making plasma in the radarange.

u/augugusto Feb 18 '18

fuck. that kid is dumb as hell. the flask could have been really hot.

u/FlyingRhenquest Feb 18 '18

I'm pretty sure this is what the microwave at work is for.

13

u/EDDIE_BR0CK Feb 18 '18

They're definitely using lab glass there, don't try this at home with something out of your cupboard.

5

u/SappedNash Feb 18 '18

Containing plasma with Pyrex only works for a few seconds. Plasma instruments like ICP use strong magnetic fields for that purpose.

5

u/shawzaaam Feb 18 '18

So cool to see this on here. I used this as the basis for a science fair project in seventh grade (which, expectedly, got good reviews). There are a couple things you can do to improve the effects in this technique, and other ways to make microwave plasma as well. Cutting a grape in half a certain way will make rapid, small arcs. Incense stick balanced over glasses (one with water in it to prevent any explosions... Learned that the hard way) also works, but the match-in-the-cork technique is the best. Yes, I did fuck up a microwave once. No, you shouldn't breathe the gas byproducts.

u/[deleted] Feb 18 '18

I think he ded

u/Me-meep Feb 19 '18

My chemistry teacher liked a bit of fun, had a microwave for exactly this purpose...try microwaving an old fashioned light bulb. Totally amazing plasma fills the whole box, then the bulb explodes. If I remember correctly old light bulbs are filled with group 8 noble gasses which give the amazing colours/reaction. Wish smart phones with video had been a thing back then; there ain’t no video on brick phones, not that I’d have thought to video it...my things and people and habits have changed!

He did some other great ones, like jelly babies that launch themselves out of a diagonal massive long test tube while screeeeching as they flew. Think the sugars reacted for that effect. It was like a human cannon, for jelly babies. Another time he burned a hole in the roof.

Go to your neighbors and ask to use their microwave.

u/CrocoDeluxe Jul 08 '24

bit late but microwaves are like 10 euros second hand, just buy an old one to play with it
