Now you must excuse me; I've got to degravitize the living room. They're due here for training in a few minutes—the Satellite One Cadets. I worked out a keyer that remotely controls the null-grav's rheostat; it's calibrated to permit creating any sub-gravitational effect from one G down to null-G. Those boys are really getting trained.
Someday I'll duplicate the null-grav over at the Project—Jim O'Brien and I have nearly got the circuitry licked—and we'll have the living room all to ourselves. Jim and his blushing bride—Gladys—come over almost every evening after the Cadets are through. We play null-grav polo, orbital chess and some other games we've adapted. Our favorite, though, is "Pick Your Planet" where we take turns imitating the orbit of one of Sol's planets, planetoids, moons or visiting comets, and pantomiming other clues.
Funny, but most often Helene or Gladys chooses Venus. With them, poor cold old Pluto's out.
Women are funny that way.
