The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
Actually that's the Coanda effect, where a moving fluid (gas or liquid) follows the contour of a nearby surface and remains attached to that surface, producing a pressure difference that keeps the screwdriver "floating".
YaKnow, IDK why, but I can't read Coanda without hearing an Aussie accent. Thanks, I'll look it up. God only Knows how desperately I need some new argumentative trivia so I can further infuriate innocent people. BwaHaHaHaHaaa...
The imperfections in the handle catch the air. As long as the velocity and volume of air is enough the screwdriver will be buoyed up. The spinning also caused by the air pressure interacting the ridges stabilizes it.
Supervisor walks up..."Aren't you supposed to be working?".
