PARIS - When peanuts are dropped into a pint of beer, they initially sink to the bottom before floating up and “dancing” in the glass.
Brazilian researcher Luiz Pereira, the study’s lead author, told AFP that he first had the idea when passing through Argentina’s capital Buenos Aires to learn Spanish. “The bubbles prefer to form on the peanuts rather than on the glass walls,” explained Mr Pereira, a researcher at Germany’s Ludwig Maximilian University of Munich.The peanuts then dive down before being propelled up again by freshly formed bubbles, in a dance that continues until the carbon dioxide runs out – or someone interrupts by drinking the beer.
The study, published in the journal Royal Society Open Science, describes two key factors in what the researchers dubbed the “beer-gas-peanut system”.
