# Simulate free fall in a rotating torus?

Say I have a rotating torus filled with air at 1 atmospheric pressure at sufficient speed (and inclined along the direction of the force of gravity with respect to Earth).

If the rotation speed were sufficient, would I be able to simulate a free fall environment for an object suspended inside the spinning torus, due to the pressure exerted by the air spinning inside the torus counteracting gravity?

• Yes, rotate with sufficient velocity to equate centrifugal force with gravitational ! – Rijul Gupta Jan 16 '14 at 22:15
