NARRATIVE
               A projectile is only acted on by a vertical force after the propulsion force is terminated. Connect the electromagnet to the Blue DC power supply, using the 6 VDC setting. A switch is mounted on the end of the gun so that the circuit is opened when the ball leaves the muzzle.

            Place the target on the electromagnet with the hole facing the gun. Aim the empty gun by sighting the can through the bore. Load the empty gun with the steel ball. Attach the tube from the gas cylinder regulator to the end of the gun. When fired, the ball will strike the can every time if it is correctly aligned. The ball will go into the hole and remain (often) after fine adjustment to the gun/target alignment.
