Make your own exploding targets with Big Blast Target Inflator Caps!

Some airgunners want to shoot quietly in their backyard so they don’t startle their neighbors. They use suppressors, and lower calibers to be as unobtrusive as possible.

This is not the product for them!

With the Big Blast Target Inflator, turn regular cola and water bottles into detonating targets! Simply add the special blast cap to the top of an empty bottle and pressurize it with a bike pump. Once the bottle is filled with air, your target is ready to go! Now when you shoot a bottle it won’t just quietly tip over--it will EXPLODE!

If you’re looking for an accessory that’s thankfully NOT backyard friendly, pick up a set and burst some bottles!

Safety considerations: 2-liter bottles are rated at 150 psi, but as your bottle will be used, it can have defects and imperfections allowing it to rupture at lower pressures. To inflate safely, cover the bottle you are inflating with a rug or heavy bath towel. Gloves and eye protection are a must while inflating and handling the pressurized bottle. Never put any flammable gases or flammable liquid or projectiles in the bottle. Stay back at least 30 feet when shooting. Never remove the cap while the bottle is pressurized, and never reuse a damaged bottle cap. Keep children and pets away from pressurized bottles.

Things I liked: great idea

Things I would have changed: 5 of them would not hold air. it would slowly leak out at 35 psi of more...will not work on drinking water bottles.(the ones you buy that wrinkle when squished)

What others should know: great idea but I will not waist my money on the sealing part should be upgraded.

Things I liked: Definitely a blast. The report generated by a 2-liter bottle is about like a firecracker or a .22 short. Was pleased to discover that they really ARE re-usable; all of mine still seem to be functioning normally after several months.

What others should know: While I am in no way advocating that users disregard instructions, I'll just say that when I first set my automotive tire compressor to 80 pounds, the bottles did almost nothing when hit. Barely a hiss. But when I bumped it to 84 pounds, I got the satisfying, bottle-busting-boom that I was hoping for. (Might just be an inaccurate gauge on my compressor...)

  • Jody from USA asked:

    What is the safe psi rating for these on soda bottles. And are they safe. Thanks

    • John from USA:

      I pump mine to 80-90 psi. Plastic soda bottles are rated to withstand 110 psi safely. Always inflate them inside the net/mesh bag that is included and wear safety glasses. John, Woodys World CEO.
