Umarex USA Big Blast Cap Target Inflator is a fun way to use a non-explosive target that merely operates by air pressure. With a Big Blast Cap you can pump air into your plastic bottle and it is recommend to pump up to 80 psi depending on the weather and size of the bottle. The pressurized air immediately disperses to normalcy creating a "boom" as the air molecules rush out into the normal atmospheric pressure.
This model includes a foot pump, 10 red bottle caps, two compatible air pump needles, one mesh drawstring bag and tie string.
