🍇⚡ Did you know grapes can create plasma in a microwave This viral experiment is not magic. It is a powerful demonstration of electromagnetic physics. When two grape halves sit very close together, microwaves can concentrate energy in the small gap between them. Because grapes are rich in water, they absorb microwave radiation efficiently. Under the right conditions, the electric field becomes intense enough to ionise the surrounding air. The glowing spark that appears is plasma, often called t
