"To get anywhere, or even live a long time, a man has to guess, and guess right, over and over again, without enough data for a logical answer."
- Robert Heinlein

Telelubricator  
  Makes any surface or substance perfectly frictionless.  

Professor Methuen has gone slightly mad and uses his considerable scientific and engineering gifts to pull pranks on his colleagues. When they try to stop him at his house, something unusual happens.

...something happened to the front steps under him. They became slicker than the smoothest ice...

Every time he applied a horizontal component of force to a hand or knee, the hand or knee simply slid backward.

So, how does it work?

"...My telelubricator here neutralizes the interatomic bonds the surface of any solid on which the beam falls. So the surface, to the depth of a few molecules, is put in the condition of a supercooled liquid as long as the beam is focused on it. Since the liquid form of any compound will wet the solid form, you have perfect lubrication."
From The Exalted, by L. Sprague de Camp.
Published by Astounding Science-Fiction in 1940

Clifford Simak was also fascinated by the idea of a frictionless surface; see the frictionless surface from his 1963 story Way Station.
