Make your own bottle blast caps

[outdoorman]

Just drill a small hole in the center of the cap for the needle valve, put in some silicone rubber in the back and let it set. Might take a day or two depending on how thick you make it. Just started trying this so still experimenting. I pumped up a 16oz Dasani water bottle to 40lbs and it works great. The rubber seals as soon as you pull the needle valve out.

I don't get it. Please explain.

A plastic bottle pumped up with high pressure air will explode when you shoot it. Just did one with 50lbs in a Dasani bottle. Nice BIG BLAST! First time I've done this. Lots on youtube for your viewing enjoyment.

Tie a string to the cap and anchor it so you can find it after.

So far, I've been shooting at the lower half of the bottle so it's the bottom that blows apart. No problem finding the top yet. Making a bunch more now. I drink Dasani water so I have an endless supply however I would like to try a 2 liter bottle. I see people charging them with 100lbs of pressure. You can put powder like chalk line chalk inside for more effect. My wife says I'm easily entertained!

What sort of needle do you use?

The needle valves for inflating soccer balls and such.

Brilliant! Well done!

Doesn't need much silicone rubber. This one worked fine on 16oz bottle pressurized to 50lbs.

Just made this short video of the affect of shooting a plastic 16oz bottle charged with 50lbs of air. Sounds like a firearm. Waiting for a donation of some 2 liter bottles.
