Operation Instructions

Pull back the spring of the slug gun.  Load the cue ball on the post that sticks out after the spring is cocked.  Place the ​other billiard ball on the side with the cup.  Level the slug gun after the balls are placed on the device as it can shift during the loading process.  When ready, lift up the string to release the balls at the same time.

Run the experiment twice. The first run is to show how the device works. For the second run, tell the class to close their eyes and listen carefully to hear that the balls hit the ground at the same time. Afterwards, the gun may be rotated away from level for the sake of comparison.
