The physics of light scattering off spheres helps explain why a grape heated in a microwave oven can generate a brilliant, highly charged gas.<\/p>\n

In dozens of YouTube videos of microwaved grapes, a plasma \u2014 a glowing gas of charged particles \u2014 flares from the skin \u2018bridge\u2019 that holds together the two halves of a severed grape. According to many online explanations, the grape halves act as an antenna tuned to the energetic microwaves. Because the moist skin is highly conductive, a current flows through this antenna and along the surface of the bridge.<\/p>\n

Aaron Slepkov at Trent University in Peterborough, Canada, and his colleagues found that this explanation is incorrect. Using thermal imaging and computer simulations, they showed that the grape halves form a cavity that absorbs and focuses the microwave radiation into a hotspot where the halves touch each other. This radiation ionizes potassium and sodium atoms in the grape skin.<\/p>\n

The team microwaved twin beads \u2014 which were composed of nearly pure water, with no skin \u2014 that were in contact with each other. The resulting hotspot at the beads\u2019 point of contact was capable of generating plasma.<\/p>\n
