A paper published Monday in a well-known science journal begins with the following sentence: “It is a truth universally acknowledged that a pair of grape hemispheres exposed to intense microwave radiation will spark, igniting a plasma.” A universally acknowledged truth indeed... but what causes this microwave marvel?
If you’re not familiar, putting grapes into a microwave to make sparks has become a popular YouTube trick.
This new research from Canadian scientists shows that worthwhile advances can come from anywhere, even by studying something sort of silly.
“This is a regime that hasn’t been significantly studied before,” one of the paper’s authors, Pablo Bianucci from Concordia University in Montreal, told Gizmodo.
The trick usually shows two grape halves connected by a thin sliver of skin.
Though various explanations exist online, researchers wanted to study the phenomenon more rigorously.
