Why is metal not allowed in microwaves?
When microwaves hit metal objects, they get reflected, which can cause problems. If there isn’t sufficient material in the microwave oven to absorb the reflected microwaves, arcing between the metal object and another part of the microwave oven can occur.
What happens if you put a metal spoon in the microwave?
The microwaves push electric charges back and forth in metal, so if the metal is too thin, it will heat up like the filament of a light bulb and may cause a fire. And if the metal has sharp edges or points, charges may accumulate on those sharp spots and then leap into space as a spark.
