Why do diced onions spark in my microwave ?Next >>
Diced onion spark in the microwave because diced onions do not contain much water. The steam pressure will be ejected from the layers of onions and forming a connecting conducting plasma. In diced onions, several chunks would need to be electrically aligned in a random manner to form an antenna for arcing and burning. These antennas will form a dielectric transmissions line and the interconnected hunks form a sort of resonant antenna to build up the large fields.
