How Microwaving Grapes Makes Plasma
Published – 02/20/2020 9:29 am
A bisected grape in the microwave makes plasma. But how does it work?
A grape is the right size and refractive index to trap microwaves inside it. When you place two (or two halves) close together the fields interact with each other creating a maximum of electromagnetic energy where they touch. This creates heating, sparks, and plasma, which is further fed with energy directly by the microwaves.
