Scientists at the University of St Andrews in Scotland apparently have found an interesting way to achieve levitation.
They found a way of reversing an effect known as the Casimir force, so that it repels instead of attracts. The Casimir force is a consequence of quantum mechanics and lets atoms stick together.
With a special lens the Scientists are able to reverse this effect.
Of course this solution only applies to nano-scale elements. So do not expect a flying Harry Potter broom anytime soon.
The importance of the discovery could lie in improving nano machines.
