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: The price is completely reasonable for what you're paying for. Ive had only one successful BOOM, a few literal bottle rocket experiences lol and a couple hissers out of 5 attempts, from the same bottle cap. Unfortunately I destroyed the first cap trying to remove it from the 5th attempted bottle with my vice, that sucker was really on there, to be fair I was a bit reckless in doing so. Believe me theyre definitely reusable. All of the fails were simply my fault I did not fill the bottle completely up to the 100 psi maximum fill. My compressors gauges are really not reliable so I remove the needle and I squeeze the bottle ever so gently to see if the bottle is reaching maximum fill. So today I just might count the time and keep record of it, until I get a successful fill time. It might take a few bottles to get the perfect time count, but its better to be safe than sorry. If anyone else is having this problem DO NOT purposefully detonat the bottle while filling thats just asking for it

Things I would have changed: NOTHING!!! The price is more than fair for what youre getting.... although a max pressure indicator on the cap would be nice. Then they could definitely bump the price up a few bucks per cap. Id def pay knowing that every time Id get a detonation, ABSOLUTELY!!! Lol instead of having to drink bottle after bottle after bottle just to see a hisser. Hahahaha I bet if anyone is even reading this they know what Im talking about.

What others should know: WARNING!!!! DO NOT SQUEEZE OR TOUCH BOTTLE WHILE FILLING!!! That net bag is to make sure the pieces dont hit you if theres a predetenation!!! Squeezing the bottle while filling is totally disregarding that safety feature!!!! HAVE FUN BE SAFE MAKE SURE TO FOLLOW ALL SAFETY RULES AND NOT JUST WITH THESE BOTTLE CAPS BUT WITH YOUR AIR GUN(s). IF THESE SIMPLE RULES ARE FOLLOWED WE CAN ALL HAVE FUN!!! DONT RUIN IT FOR OTHERS

Things I liked: Pumped 2-liter and 16-20oz pop bottles up to 100psi with a bicycle pump with a dial-gauge that goes up to 160psi. They definitely are not Backyard-friendly as my brother was 1/4 mile up the lake away from me when I shot a 2-liter filled to 100psi and he said it sounded like a Centerfire Hunting Rifle going off. 20oz bottles aren't near as loud but are still fun. A word of caution - if you watch carefully in the testing video I linked to below, you can see very small pieces of plastic bits/shrapnel being forcefully shot about by the bottles exploding. Gloves, Eye, and Hearing protection should be used when filling/handling filled bottles and any bystanders in the immediate area should at least be wearing eye protection and foam earplugs. I also would suggest only using bottles that are in excellent condition - nothing that has been crushed or distorted in any way to avoid possible weak spots in the plastic. These are not Toys so younguns should be allowed to fill/handle them under Adult Supervision or only if they can be trusted to always follow safety procedures! This video has some good info and shows how powerful the blasts can be -

  • 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.
