How Microwaving Grapes Makes Plasma

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.

      +arnav raj bet that pesky matchstick company doesn't list what ingredients are in their matchheads.... But hang on, your match is already burning when you turn the microwave on, right? Likely by then any Potassium (K) etc. have all burnt up and it's the wood or paper burning.... No? Post a response vid!! Let's check your plasma from match sticks!! Cool.

    I have several La Crosse items and they all work well. However this is the first one I haven't been able to get going straight out of the box. Followed the enclosed instructions, and then watched this video to make sure I was doing the setup properly. Both batteries are making contact with the terminals, correct polarity etc. Put it out in the direct sun for approx ten hours, even moving it occasionally to make sure the solar panel was pointed directly at the sun. Ni-MH battery is not charging, no change in the battery charge indicator. Any suggestions?

      It's kind of the 4th state of matter... solid, liquid, gas, plasma. Unlike the other states which don't change their chemistry plasma only happens to elements. Ex: water ( 1 oxygen + 2 hydrogen atoms ) can be ice, liquid water, or water vapor... solid, liquid, and gas... but you can't have water plasma... if you tried what would happen is the oxygen and two hydrogens would separate and become oxygen plasma and hydrogen plasma... and it wouldn't be water anymore. I hope this helps.

    Wow, talk about old new...this was hashed out at least 20 years ago to my knowledge at least. The grape halves are effectively converted to dipole antennas, and since their refraction and size makes it ideal for a microwave's wavelength, they swap energy between the narrow skin connecting them as the sine wave alternates between positive and negative from one pole to the other. This massive energy transfer through a small conductive media that heats quickly (grape skin), causes it to generate plasma. Also, another easy way to generate plasma in a microwave if you don't have grapes, just stick a match in a small block of wood or similar to hold it vertical, light the match, then turn on the microwave. It's usually more impressive and reliable than the grape trick.

    It it nice finally knowing exactly why. Also, seeing the plasma(because I never went longer than a spark or two) really was amazing. Just imagine, "yeah I have to go refill the grape tanks for the interstellar engine." So the grapes aid in the process of converting energy, as well as magnifying it. I wonder what the coronation between small quantities of wine, aiding in our biological processes. Could that plasma creation, with the microwaves from the sun, aid in neural connections?
