Levitation has long been a staple of magic tricks and movies. But in the lab, it's no trick. Scientists can levitate droplets of liquid, though mixing them and observing the reactions has been challenging. The pay-off, however, could be big as it would allow researchers to conduct contact-free experiments without containers or handling that might affect the outcome. Now researchers have developed a method to do just that. [1] Trying to make the perfect reaction. Trying to examine the cosmos without touching it. At the end we will succeed. And while looking at the perfect laboratory apparatus, allowing touchless chemical reactions totally isolated from the environment, we will notice out hands. (I do not touch anything) And the cosmos will not explode. And the reaction will not happen after all. And the universe will just whisper... "How can you know anything without touching it?"...
