Falling Cup with Ball Model

The Falling Cup with Ball model shows a mass attached to the inside of a cup with a light Spring. The cup is held Upside Down with the mass hanging out of the cup, then released from rest. What happens when the cup is released? The mass will extend the spring, like a Parachute, due to air pressure pulling on the cup. The mass will be pulled up into the cup by the spring? The cup will fall with the mass in its original position?
