Microwave ovens use a microwave frequency which is strongly absorbed by water molecules, causing them to vibrate, increasing their kinetic energy.
WebSo if you put your microwave meal in a metal dish, it won’t allow it to heat up correctly. Thinner pieces of metals, for example foils, can act as an antenna, which can create sparks. This is extremely dangerous and could cause your microwave to set on fire. It’s essential you remember not to put them in your microwave.
