As you spin the dowel, the center craft stick is pushed out by the wood star shaped piece until it reaches it is suddenly released causing it to snap back onto the next star point causing a “clicking” sound.  The longer you make the center craft stick, the easier it will be to rotate due to decreased tension.  Unfortunately, this will create a softer click as the stick will not hit the next point on the star with as much force.  By making the center craft stick shorter, the tension will be increased causing the stick to hit the star with much more force and a much louder click.  Of course, it will take more force to rotate the dowel with a shorter center stick and increased tension.

Try making several different sizes with various lengths of center sticks to see what different sounds you can create as well as being able to feel the difference in the tension that is created.
