Picture of Gadorade Bottle Compressed Air Gun Prank
100_0577.jpg
This is an extremely simple compressed air gadorade gun that can shoot a bottle cap 75+ feet. This project can be a fun and easy air cannon or a great prank that you can play on a friend. All that is required for this project is a gadorade bottle w/ cap, a air compressor/pump, and a ice pick or knife.

This gun makes a loud pop when fired and will surprise anyone nearby.
Depending on the air pressure this gun can be a safe prank or a powerful air gun that is dangerous. A safe pressure to play a prank would be anywhere from 10-20 psi, but as a gun this should be fired at NO greater then 45 psi . At 70 psi or greater you are in danger of having the bottle explode and that would not be very pleasant.

This is a really fun project and the videos don't due it justice.
You really have to try it out to understand, and besides it is free and easy!

Step 1: The Hole

Picture of The Hole

First you take your ice pick (or any other sharp metal object) and heat the tip on the stove. When it is hot enough to melt plastic take it off and quickly poke a small hole in to the bottle at the place where your pointer finger naturally rests. This hole should be no bigger then the size of the ball pump needle you use to fill it.

Step 2: Fill it with liquid

Now just fill up the bottle with gadorade or what ever drink you want no higher then the hole.


Step 3: Fill 'er up

All you do now is stick your air pump needle into the small hole you made (it should be snug) and fill it until the pressure gauge reads about 10-20 psi for your prank or higher for your gun. When it reaches the point you wish pull out the needle and quickly put your finger over the hole. Let your hand fall naturally into position and your ready for your prank.

u r pumping air in a bottle...then pretty much make it fart on someone and piss them off... : (
lol, imagine if a nuclear blast really happened because of a cap popping out.
Hey this is pretty cool and i have an idea on how to keep the air in without pressing your finger to it all the time. you just air it up and then quickly put a piece of tape over the whole for a temporary seal and then you melt some plastic on the stove so that you have liquid burning hot plastic and you pour that over the tape and it makes an air tight seal when it dries. somebody try this out and tell me how it works =)

The water isn't nececarry. Water doesn't like to compress, so basically you just have less volume of air in there to compress.
You are correct! The water was just my cheap imitation of Gatorade to be used in the prank!
WATER SUCKS! GATORADE IS BETTER!
gatorade tastes like water
Or does water taste like gatorade? Chicken or the egg my friend, chicken or the egg.
Chicken came first, the egg might not have hatched into a chicken, it could not be fertilized.
Ah, but what did the chicken hatch from?
it evolved from a dinosaur, one day an egg fell out o its butt
If an egg came out of a dinosaur that hatched as a chicken, then technically the egg came first.

It's a matter of creationism vs. evolution.

Creation = chicken first
Evolution = egg first.

lol. Not the palce for discussion as to which we believe. But I thought I'd throw in that neutral point.
Wow. I make 1 tounge in cheek comment and it spawns into a pseudo-scientific debate. Damn, it feels good to be a gansta.
 Awesome Office Space reference!
Hahaha. You've done well, grasshopper. Next stop . . . Spore Creature Creator. lol

Nope, there is no such thing as a chicken so there is no such thing as a chicken egg. They're just aliens in disguise. But if there were chickens the chicken would come first because its a Chicken's egg. And it wasn't a chicken's egg unless the strange evolved creature layed an egg.

Incorrect. The egg came first, because mutation occurs when the gametes combine. The proto-chicken laid an egg which mutated in development into the chicken we know of today. Bam.
Actually I believe Chuck Norris came first. He made both the chicken and egg at the exact same time.
waterboy reference? lol : D
dont u need the water to stop the air from coming out
notice how nobody pointed out that it's not a gatorade bottle you used. its really a powerade bottle.

Does the electrical outlet function of that compressor work?
Kaiven6 years ago
Idea! just put vinegar in with some food coloring, then add a little bit of baking soda and seal it. It will stay sealed nutil you pop off the lid.

He cool but i am going to try mod it so you don't have to hold the hole when it pops. My dad makes water rockets were we shoot the bottle we usually go 80-100 psi and it goes awesome high!
I know! i made some with my dad that go a couple hundred feet high!
only a couple of hundred, meh. we made a water cooler explode!
i know it has been a while, but have you modded this ible yet? i would like to know so i can make a good one :P
dang! Oh dang something else! my nuckle is bleeding for some odd reason, and im typing with one hand since im eating pizza
That was probably the most random coment i have ever heard...
well, it was randomly bleeding, and i was eating pizza and typing with my cut knuckle LOL
Maybe it was not so random pizza sauce. lol One could hope.
nope, a perfectly straight indent into my nuckle. gone now, i hope. its been over a 2 months xD

Let me know how you modify it to keep air in so that I can try it out Thanx for the vote and the rating
kentjoe (author)  duck-lemon6 years ago
I found out that the bottles don't usually burst until 150+ psi so I may try it out at higher psi and push those bottle caps to the limit. I used a piece of clay and pushed it in the hole and that worked fine at under 40 psi to block the air from escaping. I also weighted down the cap with clay to make it shoot further and more accurately.

try copressing it with viniger and baking soda in it also.
That bird needs to shut up in ur vid
Sun Gear6 years ago
you can do this with soda
BE EXTREMELY CAREFUL! when filling up the bottle because once me and my friend were trying to make a rocket but it wouldn't shoot so we figured iout that if you hit with a stick while its pressurized it will explode but unfortunately i was the unlucky person to do it and the cap flew off at 150 PSI and it hit me in the butt so i couldnt sit down for 2 days
i have a modifying idea get a bicycle inter tube and cut off the nozzle but like a cm around it of the rubber. drill a hole big enough for the nozzle and put glue on the rubber and shove it thew, no need for water! just do like 70 and boom!
kentjoe (author)  struckbyanarrow6 years ago
Great Idea! I just aquired a inertube yesterday and I was Trying to figure out a way to use it for my bottle gun. I gotta try this out. Thanx
np
Ingenious. My Junior High would sell water bottles with the lunches, so my friend and I would twist the bottles to build pressure, then watch the cap fly. your way is infinitely better. I gotta try this sometime. +1'ed, Voted, Fave'd.

What in gods name is that squeaking? lol
kentjoe (author)  jonnyboy3236 years ago
The squeaking is my sisters bloody birds. Time to use my gun for a more practical purpose! I look forward to more silent videos in the near future.
