      Spoon’s [almost definitely] fine. Foil can do it though, especially crinkled up like that.

        The spoon can actually mess with the evenness of the heating even more than the foil. It won’t be as dramatic about it though. Unless there’s something flammable at the focal point, then it can get real dramatic.

    Lol I’m 40% sure this is a joke, but in case it isn’t: if you place conductors in the microwave: sometimes it’s a spoon, sometimes it’s the silver lining on a plate, or you can go overboard and throw actual aluminum foil in there for good measure…the microwaves drive a current in the conductor **, which creates sparks from lots of tiny arcs…lightning indeed my friend :D

    Suggestion: Forks are particularly spectacular too

    PS: the foil should act as shielding against the microwaves, so I predict that the content won’t warm up, but maybe the hole is enough to let it heat it a bit :)

    ** If a conductor is not convex (e.g. fork, crinkled aluminum foil), each crease acts as a capacitor, so when the microwaves drive (through resonance) a current and overcharge the capacitor plates, they short the dielectric (the air in this case) and create the arcs.
