The bell curve of microwave knowledge is painfully accurate. The 100 IQ crowd parrots "metal in microwave = bad" without question. Meanwhile, the true idiots and geniuses both know the secret: it's all about the shape!
Metals with sharp edges or points create electrical arcs as electrons accumulate there (think: fork = fireworks). But smooth metal like spoons or those Chinese takeout containers with metal handles? Totally fine.
Next time someone gasps when you put that soup bowl with the gold rim in the microwave, just smile knowingly. You're either at the brilliant end of the curve or... well, let's hope it's not the other one.
