Items You Should Never, Ever Place in a Microwave

Aluminum foil

Any metal, foil, or metallic edging on a plate will nuke your microwave. No metals allowed! Thin metals, like foil, generate even more danger than thick ones: in the latter case, like when you put a frying pan with thick walls into your microwave, your food just won’t ever heat — the metal reflects microwaves, and they simply don’t get to what’s inside. However, thin metal gets overwhelmed by electric currents generated inside the microwave, and heats up very quickly, making the danger of fire a very real thing.
