Here is how to make a water bottle noise maker. You need:
-water bottle
-drill
-pop in tire valve
-bike pump

First get your water bottle and drill a hole the same size as your tire valve on the side of it.




Now pop in the tire valve into the hole that you just drilled. The finished product should look like this.






Next you pump up you water bottle NO MORE THAN 5 PUMPS!! It WILL explode. Like shown in these pictures...





Twist the top off as fast as you can and boom. Your noise maker. Heres a video of it in action.

Heh heh... this is almost the same thing we do at school, (ovbiously not exactly the same).

Just take the bottle with the cap on, take the two ends of the bottle, (one in each hand), and then twist. Twist it into an hourglass shape until you can't twist it anymore because of the pressure, and then loosen the cap just slightly. Then, flick off the cap and it does the same thing, except quieter. Good thing to do if you don't have a bike pump at school with you.

Thats where I got the Idea! I mainly use this to piss off the neighbors.

Another thing that works instead of twisting is folding it in half. When you where pumping it up you had your foot right next to it. That would really hurt if it blew !!

Hahaha, thats great. Man, that was cool!
At first I thought you meant for it to explode. That looks like fun bit a little dangerous. Specifically because you hold it in your hands.

Why not use a soda bottle so you can use higher pressures? Also, ' five pumps only' is a bit vauge, it all depends on the pump your using and the size water bottle. Does your schrader leak? I've found the best way to mount them is like this. It seals perfectly, is removable, and I have taken them up to 100psi without ANY leaking. I will try making the 'noisemaker' and see how loud it is. I already have a bottle with a scrader from one of my other guns.
Anyway nice how to!

Very nice prof I can do this to annoy the neibors jk.

Why not use a soda bottle so you can use higher pressures?

Because you can't get a soda bottle cap off that fast. I've tried it a million times and can't do it.

WOW! I just tried it. At 80 psi. I couldn't get the lid off, so I sat the bottle on it's side and 'kicked' the lid off with my foot. The grip on my shoe spun the lid real fast and BOOM! It was fairly loud and the lid went flying. I tried again and could't do it, as I only had thongs on it was hard toget it to grip.

Its fun and the five pumps thing is a saftey measure. The one that I exploded was on purpose in contained very safe conditions. It was barried 2 feet below ground in a 6in pipe filled with dirt and had a wheel barrel as another safety cover. It took 105 psi or something like that before it blew. This means that I did the experiment so that you didnt have to. With five pumps on my valve its creates ~ 30 psi. Just be safe and dont losea hand.

LOL!!! I tried this just now and I put a vice grip on the cap so i would have a lever to open the bottle faster and it ripped the vice grips out of my hand and threw them like 4 feet! This would be mean but funny to do to somebody. fill the bottle like halfway with water so it looks like its normal, pump it up, put it in a water bottle insulator thingy so you cant see the schader on the bottom and hand it to someone!

OHHH I have an idea! Because its so hard to get coke bottle lids off fast enough, jam a cork into the neck of the bottle, then screw the lid on. the lid wont have to hold any pressure, just hold the cork in. So even if the lid comes off slowly it will still go POP! Somebody try this and post your results, I don't have any corks so I can't try this.

Hey that's like the pneumatic version of my ghetto coke bottle fireball doohickey.
Don't listen to what I'm saying, I was making my sis laugh, and I sound dumb.

It would still have the same pressure on the cap just instead of the air directly on the cap it is pushing on the cork which is pushing on the cap.

Ooooh Thats soooooo cool I might have to go try it!
