Swiss scientists use sound waves to levitate and manipulate objects, such as water droplets and a wooden toothpick, in mid-air.
Every month, there seems to be news of some fabulous science fiction concept that is ever closer to becoming science fact. In just the past few months, we’ve seen concepts go public for medical tricorders, augmented reality glasses, smart watches (although how much we actually want them is up for debate) and Jurassic Park-style de-extinction. Now, enter levitation, which could very well be the next science fiction concept to hit it big.
If all goes as planned, it may soon be possible for pharmaceutical researchers to levitate molecules in mid-air and for city planners to build super-fast transportation networks filled with levitating vehicles.
