PizzaQ, 4 slices with endives and mushrooms.
At left is a closed-circuit television image of a Royal Canadian Mounted Police officer standing at attention holding a purse.
He's standing in a windowless room in front of rectangular graph paper wallpaper. The room could be an ordinary room on the surface of the Earth (bottom right).
Or the room could be on the spinning Carousel which uses centripital force to generate Artificial Gravity on Elmer's Space Taxi which is in deep space on a voyage to a distant planet (top right).
If it's the Space Taxi Carousel, it's big enough so you can't see any curve to the floor in the little room. Just like an Earth floor -- if there's a curve, it's not big enough to see.
The Mountie can hear you, so you can give him an order -- like turn around, or jump up, or do pushups, things like that.
Give the Mountie one order which will clearly, unambiguosly show you whether he is standing on the surface of the Earth, or whether he is spinning on the Carousel on Elmer's Space Taxi in deep space.
(The floor is made of wood and the Mountie is not wearing magnetic or Velcro boots. He's standing on the floor just like you stand on a floor, no tricks.)
