Bring the boom with Umarex®! Using old plastic bottles and air pressure, the Big Blast Target Caps turn a normal day of plinking into explosive backyard fun. Caps utilize innovative valve material that allows normal plastic soda & water bottles to be pressurized making them reactive exploding targets. Simply attach the reusable caps to old water bottles, fill them up, and watch them go BOOM!
How does it work?
Simply attach the Big Blast Cap to an empty plastic bottle…anything from 16-oz. bottles to 2-liter bottles. The bigger the bottle, the bigger the boom. Using an air pump and an inflating needle (included) pump the bottle up to 80 psi depending on the weather and size of the bottle. Place it down range at least 60 feet away and shoot it with a projectile. The pressurized air immediately disperses to normalcy creating a "boom" as the air molecules rush out into the normal atmospheric pressure. Note: Eye and ear protection are recommended for anyone in the vicinity of the blast.
