SUMMARY

Microwaving a grape can produce plasma due to the unique structure of the grape, which contains moisture and a skin that can create a concentrated electric field. When microwaved, the water inside the grape heats up rapidly, leading to the formation of steam and a subsequent build-up of pressure. This pressure can cause the grape to burst, releasing energy that ionizes the surrounding air, resulting in plasma. The phenomenon is not well-explained by scientific literature, leading to various interpretations and opinions among forum participants.

Hello.
Do you know that if you take grape to the microwave, you can make some plasma? I think so.

However, on internet is a lot of explanation why does thegrape in microwave produce plasma, but they are not good or they are different. I don't know some official theory.
So, I have a question about your view why does the grape in microwave produce plasma. No links, no internet, only your view, i really was searched it.

You are asking for opinions, not Science. So you may want to reword your question.
 
I've generated plasma in the laser lab any number of times. From the video, this appears to be a plasma.

Why does it generate a plasma? Not clear to me, and I hate to guess.
