Microwaving a grape can produce plasma. This is a known process, but for what purposes? Provide examples if possible. Thank you and Happy New Year!
Maybe it gives information about the sensitivity of eyes to microwaves?
Only one thing seemed certain. Put in a microwave oven, a grape produces a luminous plasma. The most popular hypothesis advanced the importance of the small bridge of skin left between the two pieces of grape. It is indeed rich in electrolytes. As for the exposed aqueous surfaces, they were presented as facilitating the propagation of electric current. Doubting these conclusions, Canadian researchers have studied the subject very seriously. They first placed in a microwave oven whole grapes, arranged one against the other, and up to a distance of three millimeters from each other. Then, hydrogel beads almost made of pure water. Result: in both cases, they observed the formation of a plasma. "Neither the skin of the grape nor the wet surface therefore seem essential in this area", concludes Hamza Khattak.
