Comically enough, many spoons put in the microwave would be fine. Not recommending you try it, but the issue comes from arcs. And spoons don't have areas where arcs can occur naturally, like a fork.

[-] disguy_ovahea@lemmy.world 9 points 2 weeks ago* (last edited 2 weeks ago)

It also depends on the condition of the nickel plating. Scratched up cheap stainless would probably arc.

[-] potoo22@programming.dev 8 points 2 weeks ago

To my understanding, the arcing is caused by hard edges. E.g. all the elections could be at the end of a fork's tines, and EM field forces them to jump to another tine instead of going through the root of the fork.

Since spoons are rounded, they don't need to jump. I don't think the material plays much of a role in arcing other than providing resistance. They would heat up, but they'd melt before they arc. Still, they can arc from one spoon to another spoon when there multiple spoons close enough.

[-] disguy_ovahea@lemmy.world 3 points 2 weeks ago

Absolutely. It’s far more likely with a fork, but deep enough or well placed scratches/gouges on a spoon could create the condition.

[-] onslaught545@lemmy.zip 3 points 2 weeks ago

It's unlikely period. Electroboom did a video on it and had one hell of a hard time getting any metal to arc in the microwave, even balled up aluminum foil.

[-] emeralddawn45@lemmy.dbzer0.com 1 points 2 weeks ago

Well that just doesnt make sense, theres only been a couple times ive accidentally put metal in a microwave, but i knew it immediately when i did. I wonder if theyve made changes to the way they function.

[-] olafurp@lemmy.world 1 points 2 weeks ago

There has been no change in the way microwaves work aside from circuit board and adding an inverter to control the power of the microwaves. Microwaves function the same as a laser pointer except the emit photons with a frequency of 2.45GHz.

[-] LifeInMultipleChoice@lemmy.world 1 points 2 weeks ago

I'm lazy and don't use tik tok, but from what I've seen when my spouse is on there this would make an interesting tik tok channel (is that what they are called?). Spoon Spark, where someone collects a shit ton of spoons and people take their guess on whether or not they'll spark or even start a fire. Maybe get different power levels of microwaves to increase to throughout the tournament.

The E-Waste Arc Spark competition.

[-] SubArcticTundra@lemmy.ml 3 points 2 weeks ago

That's so stupid. But also quite interesting lol

[-] olafurp@lemmy.world 4 points 2 weeks ago

https://youtu.be/OyTmJX_TC84 Here's a YouTube video of a guy actively trying to make arcs.

[-] potoo22@programming.dev 3 points 2 weeks ago

The contact points between the spoons will heat up and may melt or spark.

[-] LifeInMultipleChoice@lemmy.world 1 points 2 weeks ago* (last edited 2 weeks ago)

You mean like a spoon on a glass or ceramic plate? That seems unlikely.

There is even companies that make glass/stainless steel lids for their microwave safe containers. So the lids won't warp like the plastic ones do and have to be thrown away

[-] gens@programming.dev 2 points 2 weeks ago

No, he means that the small points will arch electicity, leading to more stuff

[-] Agent641@lemmy.world 2 points 2 weeks ago

I microwave my coffee with a spoon in it every morning at work, it's fine

[-] toynbee@lemmy.world 1 points 2 weeks ago
[-] LifeInMultipleChoice@lemmy.world 1 points 2 weeks ago* (last edited 2 weeks ago)

Yeah I know it uses waves towards the center but they are throughout the microwave, yet people don't questions the holes in the metal siding, which are metal circles. So if arcing was an issue on smooth sutfaces, it should happen there as well.

[-] kameecoding@lemmy.world 1 points 2 weeks ago

Yep, I have microwaved plenty of tea and coffee with the spoon in it.

[-] toynbee@lemmy.world 1 points 2 weeks ago

Spoon or not, I'm told this is a sin.

Perhaps including silver purifies the act.

[-] kameecoding@lemmy.world 0 points 2 weeks ago

If you mean like, by the standpoint of coffee purists, then idgaf, it's shitty tasting make brain go fast water, there is no way to ruin it, how can something that tastes like shit taste more shit? It can't

[-] olafurp@lemmy.world 1 points 2 weeks ago

Lol, gottem

[-] toynbee@lemmy.world 1 points 2 weeks ago

I don't drink coffee and rarely tea, so you won't get any argument from me.

[-] MotoAsh@lemmy.world 0 points 2 weeks ago

Why torture yourself by not caring about the taste? Even shitty black coffee can be made to taste alright unless it's burned to hell.

[-] kameecoding@lemmy.world 0 points 2 weeks ago

No it can't, coffee doesn't taste good.

You might disagree, but this is subjective, so...

[-] MotoAsh@lemmy.world 0 points 2 weeks ago

Meh. Coffee can be made to taste like not-coffee, so you're quite literally objectively wrong either way.

[-] kameecoding@lemmy.world -1 points 2 weeks ago* (last edited 2 weeks ago)

You are weirdly defensive about coffee

Not to mention your point makes no sense, ofc if you make it taste like something like not coffee then it won't taste like coffee, but then that defeated the purpose of discussing the taste of coffee, drown it in enough sugar and milk and ofc it will taste good, like add it to a tiramisu and you are not even tasting coffee just a hint of it

[-] Treczoks@lemmy.world 5 points 2 weeks ago

What's those balls on the plate?

[-] Agent641@lemmy.world 14 points 2 weeks ago
[-] Klear@lemmy.world 2 points 2 weeks ago

lmao gottem

[-] Honytawk@lemmy.zip 2 points 2 weeks ago

Either magnets or ball bearings. Most probably the magnets.

[-] MotoAsh@lemmy.world 1 points 2 weeks ago* (last edited 2 weeks ago)

Nah, even weak magnets bunch up really easy, at least to make a solid sheet with noticable crystaline-like deformities being the only exception to a contiguous layout.

Those balls are sitting way too loosely with way too many random gaps to even possibly be magnetized.

[-] Zier@fedia.io 2 points 2 weeks ago

Not enough balls. Happy National Bomb Day America!!!

[-] pitaya@lemmy.zip 2 points 2 weeks ago

Make the foil spiky to be on the ~~safe~~ side

[-] diemartin@sh.itjust.works 2 points 2 weeks ago
[-] JATtho@lemmy.world 1 points 2 weeks ago* (last edited 2 weeks ago)

Sure it's terrifying, but you can start a sparky plasma show in a resilient enough container and keep it going for hours and the microwave won't break. (except maybe overheat.) The microwave will be fine as long as the arcs don't reach the waveguide cover. (which would risk burning/shorting the magnetron.)

I have done the microwave grape plasma trick myself and started an arc in a microwave. The current between the two objects goes through a very narrow point, which is enough vaporize the contact point to plasma. This then can grow as the microwave continues to pump more energy into the spark.

[-] HeyThisIsntTheYMCA@lemmy.world 1 points 2 weeks ago
