How Microwaving Grapes Makes Plasma

182568 ratings | 8088696 views
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. Linking plasma formation in grapes to microwave resonances of aqueous dimers https://www.pnas.org/cgi/doi/10.1073/pnas.1818350116 Special thanks to Patreon supporters: Donal Botkin, James M Nicholson, Michael Krugman, Nathan Hansen, Ron Neal, Stan Presolski, Terrance Shepherd Thanks also to Steve Bosi, my original plasma collaborator.

If you need help with some of the audio, turn on captions!

It's alright I already have the subtitle captions

The sodium was because of the glass that the plasma was contained in

So how does this explain the plasma Wbeaty gets by preheating glass then microwaving it? https://www.youtube.com/watch?v=cskB5c0mJ58

The resveratrol in the grapes probably has something to do with the plasmagenesis.

@5:50, was that a statement, or a question?

I've seen carrot pieces spark, as well wet dog treats coincidentally the size of a grape. I've read it's due to minerals (carrot pieces), but I'm now wondering if this is due to a similar heating/ionization of the air (with the meat treats, probably due to the size of them?
Jack Adrian Zappa (3 days ago)
> 04:52 > with the very strong electromagnetic fields at the intersection of the two electric fields are strong enough that they ionize the air creating those Sparks and that is what leads to the plasma it creates these ions which can then receive more energy from the microwaves. How does the electromagnetic field intersection ionize the air? Is this heating that one spot in the grape, imparting enough heat to cause the air molecules nearby to lose electrons? Or is it focusing the radiation to a single point and the air is close enough to then absorb the radiation energy to then lose electrons? Or something else?

Actuary similar phenomenon is already used in the opticalregion, called localized surface plasmon. They are used to confine optical energy to a tiny space, using two small metal particle faced closely eachother like grapes in this video. Main application can be seen in SERS(Surface-enhanced Raman Scattering). Sorry for my poor english :(

You get plasma from smoke from a match as well so I thought it was from the smoke from the grapes being burnt .

Why normal folks dislike smart-ass scientists and pseudo-experts is their know-it-all attitude. They could have gotten a regular, college guy with a good voice who shaves and talks normally... and not a prick

Hi, I think you should bleach your teeth a bit more. Just to make sure EVERYONE notices that you bleach.
poikaa3 (18 days ago)
Raindrop reflection of radio waves at certain frequencies is along these lines but a microwave is itself a resonate cavity, a microwave is also a shielded box to contain the microwaves. there is a stirring action (fan paddle) of the microwave box to angle the wave pattern for even heating.

i thought it was really cool learning that orbies work just as well as grapes. For this experiment, I assumed that cut grapes needed to be used to create this experiment. But apparently, two whole grapes touching do the same thing.

All this did was disperse energy between two objects, because you added an energy source to the reaction. No energy no reaction, just like any battery.🤔
