The next GEN will have food  flying directly into their mouth

The restaurants of the future may have food floating directly into your mouth, as scientists have developed a technique that can levitate tiny amounts of eatables using sound waves.

Researchers from university of Sussex in the U.K. Discovered how to tune high frequency sound waves make almost any food stuff float if it is jot bigger than a pea size. Acoustic levitation works by creating a powerful standing wave of sound this can trap all objects in a kind of cage of sound waves.Scientists say that one could even use this to give medicine to children to make the process of taking in medicine fun for children.
