You can't. You can simulate the feeling of weightlessness by flying a plane in and up-and down, sine wave-like arc, but that's really just freefall. Even in Earth orbit you're under what's called "microgravity." You'd have to get pretty far out into space to be truly weightless.

If you get into an elevator on the 10th floor, cut the cables, you will be weightless until you hit the ground. This is not practical for scientific experiments, so they use the "vomit comet", an airplane that follows a parabolic trajectory in the atmosphere, which is essentially free-fall.

Work completely submerged in water, Fly an air plane in a parabolic curve.

centripetal force generated in a round room which rotates very fast.
