Put the cutlery* down. Food could soon be levitating into our mouths. Researchers have found that high-frequency* soundwaves can be tuned to make delicious objects float. And scientists at the University of Sussex say the process even makes it taste sweeter. There is a catch though — the food must be no bigger than a pea. Marianna Obrist, who works at the university, said: “It’s more like something you would use when you just want a taste.” The process sees a small object trapped in a cage of soundwaves which leave it weightless. Chi Thanh Vi, also from the University of Sussex, says levitation* makes food taste different. “Sweet tastes feel more intense and bitter tastes people find quite pleasant,” he said. This feature could come in handy when trying to persuade children to eat their greens or take bitter medicine. Thanh Vi said: “If you make it fun, if you make floating medicine, sure they would go and give it a try.” (SD-Agencies) |
