ABSTRACT:
An apparatus for simulating a lower gravity environment. The invention allows individuals to experience a simulated reduction in the gravity of Earth. A large balloon provides a buoyant upward force. The balloon is attached to a sturdy frame which is secured to a harness for anchoring the individual to the apparatus. The frame is attached to the balloon with a rotating hinge, allowing for horizontal rotation of the individual. The frame may also attach to the harness with a rotating hinge allowing for vertical rotation of the individual.
