    Either magnets or ball bearings. Most probably the magnets.

      Try it outside in your backyard.

          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.

            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.

            I learned this by accident while heating up some hot cocoa as a kid, haha!

              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.

                You can also do this by blowing out a match and putting it under an upturned glass shortly before microwaving it. Turns the carbon vapor into plasma, or some such. Though the time I tried it, it escaped the glass and melted the microwave's lining. Don't recommend if it's an appliance ya care about.

                  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.

                  EM fields concentrate from the edges, like how magnetic field lines concentrate around a paperclip hanging from a magnet. It's not about charged particles being able to retreat, but that the EM field will straight up be stronger in those areas.

                      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.

                      Not really. The case should be grounded, so even if it were causing a charge differential in the metal, it'd just make a current to ground (or back to the neutral magnetron pole if it's not grounded). Although 'current back to ground' is likely misstating it, since it'd be an AC induced current that wouldn't be moving too far and ultimately just heat up the metal in place without electrons doing much more than wobbling about.

                      Metal in the microwave can create arcs because the metal is surrounded by the microwaves with no conductive path anywhere, so charges can just slosh around more and more as power is applied. Get a large enough charge built up in some area that it has the potential to jump through the air to a less charged place, and bam, arc.

                      It's like the difference between pushing someone on a swing that cannot go somewhere else vs pushing someone sitting on a skateboard (or an insanely tall swing on the ungrounded case). Only one of those cases makes it easy to build up more and more swing.

                      The door works fine because the holes are too small to even let the waves through, so there isn't a big fluctuating EM field all around it to produce much of any different charge potentials to cause current to flow, so no sloshing charges and no real heating.

                        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

                        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.

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

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

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

                                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
