This NASA video segment explains why objects seem to float in space. Viewers learn that objects on board the space shuttle, as well as the shuttle itself, are in a continuous state of freefall. To demonstrate this effect, a boy holding a ball jumps on a trampoline. An astronaut describes how gravity acts on the boy and how, for a moment, the ball seems to float. Viewers are then asked to think about how gravity affects the way astronauts live in space.
