Levitation by anti-stick

Casimir force, which basically causes very small things to stick together (I’m not sure if they use that exact definition in quantum physics textbooks), has now been harnessed to levitate objects. Well, objects on a very very small scale.

By reversing the Casimir force by using a special lens, scientists have at least in theory created a solution to one big problem in nano-technology: as the mechanical devices get ever close to one another, sticking together becomes an issue.

And no, you can’t levitate humans with it. Yet.
