How Does Microwaving Grapes Create Plumes of Plasma?

Question

When grapes are microwaved, they can create plumes of plasma. This phenomenon occurs due to the interaction between the microwave energy and the water content within the grapes.

HackerNews · Accepted Answer

Microwaving grapes creates plumes of plasma due to the formation of hotspots and the ionization of water molecules. When grapes are heated unevenly, they can create regions of high temperature and electrical conductivity. As the microwave energy continues to interact with the grapes, it can ionize the water molecules, producing a plasma. This plasma is then released as a plume.
