The Soda Popper(TM) Pneumatic target provides a high decibel audible report when struck by BB, Pellet, Rifle and Pistol rounds or Arrows.  Simply screw a discarded 2 liter soda bottle into the threaded portion of the base, inflate to the appropriate pressure and place at a safe distance from shooter and observers.  The Soda Popper is re-usable and, with proper care, will last indefinitely.  (Note:  Product comes complete and ready to use.  However, after extended use, the user may have to replace the sealing O-Ring(#15, 1"OD x 3/4" ID x 1/8")
