02. If we are floating, how will we know which way is up and which way is down? If the floor and the ceiling look alike, how will we know which is which, or doesn't it matter? (A K2S Question)

What we have found is that when you float into a room, you think the ceiling is above you, and the floor is below. If I happened to enter sideways— for example, if I got a little twisted as I flew through the tunnel to the space lab—and started floating along the side of the tunnel instead of along the bottom and then entered the space lab with the side wall beneath me, my first thought would probably be "Gee, the floor looks strange today!"
