How Microwaving Grapes Makes Plasma

YouTube description:

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.

The grapes shall fear us now.

They always were thin skinned.

The grapes shall fear us now.

"The angel swung his sickle on the earth, gathered its grapes and threw them into the great microwave of God’s wrath. They were cooked in the microwave outside the city, and plasma flowed out of the microwave, rising as high as the horses’ bridles for a distance of 1,600 stadia."
-Revelation 14:19-20

The grapes shall fear us now.

And now we know the history of the phrase "grapes of wrath"

"The angel swung his sickle on the earth, gathered its grapes and threw them into the great microwave of God’s wrath. They were cooked in the microwave outside the city, and plasma flowed out of the microwave, rising as high as the horses’ bridles for a distance of 1,600 stadia."
-Revelation 14:19-20
