How Microwaving Grapes Makes Plasma

The video explores the phenomenon of creating plasma by microwaving grapes, a concept initially demonstrated in a previous video. Recent scientific research has provided a detailed explanation of this effect, revealing that microwaves become trapped inside the grape due to its high refractive index, forming resonance modes. This leads to heating from the inside out and, when two grapes are in contact, creates strong electromagnetic fields that ionize the air, forming plasma. The video also discusses potential applications in microchip lithography, highlighting the ability to focus electromagnetic energy to a tiny spot.
