Look at the balls right when they come out of the marker.... they are spaced evenly at about 20 ft...... this is a great example of the newtonian laws of physics haha. An object in motion stays in motion unless another force acts upon it. Well air acts upon the balls and slows them down which makes them come closer together since they are no longer speeding away from the marker.
