Scientists Make Very Small Objects Levitate

A natural force which causes tiny particles to stick to one another has been reversed by scientists, effectively enabling them to create a type of levitation.

The "Casimir force," which is sometimes referred to as a "sticky quantum" force, makes very small "nanoparticles" attract one another. One example of it is a gecko's ability to stick to any surface with one toe.
A pair of physicists at the University of St. Andrews in Scotland have discovered a way to reverse the force, meaning that they can make small objects repel, rather than attract, one another in a vacuum.
