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.
    Huge thanks to Hamza Khattak, Prof. Pablo Bianucci and Prof. Aaron Slepkov (unavailable for the call) for chatting to me and helping me understand the physics of this cool phenomenon.

      +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 did this with a potato. I've cooked many potatoes in the microwave but this one turned to charcoal in a couple of minutes.
      I had no idea why until now.

    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?

      Also, why does the index of reflection goes up in the microwave? Is it because microwaves have longer length than light?

    But what is Plasma???

    • Mike Sullivan
      Mike Sullivan 2 days ago

      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.

  • Skinflaps Meatslapper

    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?

    New breakthrough in matter:energy conversion renders all forms of energy redundant instantly. Even the 2kg of antimatter I have painstakingly collected may as well just be poured down the sink. Instead grapes have become the densest form of energy known to man. Who needs cold fusion?

    ur analysis is very helpful. inside the grape, the velocity of the microwave becomes 10 times slower. so the wavelength of the wave becomes shorter. the resultant wavelength is equal to that of diameter of the grape. thats why inside the grape, a standing wave has occurred, so outside of the grape man can observe the microwave is trapped. if those two grapes are placed as far from each other as the wavelength of the microwave, an oscillation therebetween has occurred. around the contact point according to the strength of the oscillating microwave, air molecules have ionized. the ionization continues because of the supply by the electromagnetic field.
