   You lost; they exist all right.   
      
   Take a sturdy enough box, crawl inside, and have some other people lift   
   it, then drop it. Alternatively, have them push it over the edge of a   
   table. From the time the box lost contact with the helpers' hands / the   
   table till it hits the floor, it will have the same acceleration as that   
   of gravity, and inside there will be no percieveble gravity. There's the   
   anti gravity chamber.... Thinking about it, it's probably safer just to   
   jump from that table, but then there's no chamber.   
      
   The drop towers are higher variants of the same, with the added feature   
   of a brake, so you won't get killed at the bottom. Airplanes can fly in   
   trajectories that effectively cancel gravity (perception) for a minute   
   or so (again, it's cheaper to pull out before the plane hits the   
   ground). Spaceships in orbit can follow such a trajectory until the   
   passenger has been convinced and just wants to go home.
