>> This is a floating beef burger, and it might just become a new craze in dining. The TastyFloats prototype uses acoustic levitation to suspend tiny bits of food and drink in mid-air. That's done by trapping the portions, such as this corn flake and orange juice breakfast combo between very high frequency sound waves emitted from two low-cost ultrasound speakers.
>> What we found out is the levitating taste in there is more intense compared to the taste outside. So you feel the sweet taste, for example, is sweeter.>> Researchers at Britain's Bristol and Sussex universities have also floated the idea of tasting nights with local chefs. Levitating minuscule meals straight from the kitchen to the tongue without ever touching a plate or cutlery.
But researchers say more work is needed to explore how this tech could fit into real life situations. And that's mainly about raising the portion size.
