SMALL RUBBER ACTIVATOR
This Small Rubber Activator has a triangular shape so it sits on any flat surface, or in the palm of your hand. It is the perfect softness of rubber to activate the sound without damaging the fork or interfering with the vibrations. We don't recommend hockey pucks for this reason - the rubber is too hard. You only want to hear the sound of the fork, not the sound of the activator.
