"In my mind I have gone all over the universe, which may make it less important for me to make piddling little trips... I did enjoy seeing Stonehenge. It looked exactly the way I thought it would look."
- Isaac Asimov

Bolt Anti-Grav  
  This device produces a torus-shaped discharge that causes weightlessness.  

“Bolt anti," she whispered as her breath began to come back. "Not much good, but best I could do. Government's cracked down on all anti sales since the geeksters began using them." She fumbled with the end of her shari and produced a flat, blunt object like an old-fashioned air automatic. She handed it to George.”

He examined it distrustfully. He had always considered the bolt anti-grav the most unreliable of anti-gravitic devices. The anti-gravs in commercial use (most strictly supervised, since geeksters and raubsters had discovered their value in mass levitation of stolen goods) were perfectly safe. But the bolt anti-grav worked on a different principle. Its "doughnut" discharge produced what non-material physicists called a reversed stasis of the object which it hit. The object in consequence became weightless. The difficulty was that there was no practical way of estimating in advance when the stasis would return to normal and the object acquire weight again. And, since stasis reversal was potentially harmful to living tissue, all bolt antis had built-in governors preventing their discharge too frequently. Too dangerous for a children's toy, too ineffective for genuine use, the bolt anti was the perfect example of ingrown gadgetry.

This is how it feels when it strikes you:

The doughnut hit him amidships just as he jumped. It spread over him in a kind of shudder, a sensation like an intense interior tickling, not painful, but highly disagreeable. Then he was soaring over the roof in a long, long arc...
