Physicists said they can create "incredible levitation effects" by manipulating so-called Casimir force, which normally causes objects to stick together by quantum force.
The phenomenon could be used to improve the performances of everyday devices ranging from car airbags to computer chips, say Professor Ulf Leonhardt and Dr Thomas Philbin from Saint Andrews University.
Casimir force -- discovered in 1948 and first measured in 1997 -- can be seen in a gecko's ability to stick to a surface with just one toe.
Now the British scientists say they can reverse the Casimir force to cause an object to repel rather than attract another in a vacuum.
"The Casimir force is the ultimate cause of friction in the nano world, in particular in some micro-electromechanical systems," said Leonhardt, writing in the August issue of New Journal of Physics.

I guess I'm not getting my flying car anytime soon either.
Now... if my super miniaturizing machine would work tonight... I... I just might be able to take over the world.
Mwu ha ha ha hah.
Alas, it wouldn't be much fun to be atomically small.
I have a ray that will swell the heads of TV weather guys who steal my catchphrases. Mwu-hahahahaha!
On top of that, I have a box of red, white and blu popsicles.
Human levitation is currently available, via Viagra. Like the Casimir force, it has the effect of causing objects to stick together, too.
