The Big Potato Gun Air Cannon Experiments 2

[metalstorm91291]

My cannon is a bit smaller; it has a 10 foot barrel and a single, 10 foot air tank made out of 2" PVC, and It'll still shoot a large-diameter dowel "dart" - which weighs about 1.2 lbs - at about 300 fps with only 60 psi in the tank. That translates to about 1,700 ft-lbs of energy. I can't imagine what yours would do with a similar load. Keep up the good work!

if u want to put something in it put a javelin in it that would be mad

[JacobBassMaster]

my cannon shoots 20 oz watter bottles like 1/3 of a mile

i have a good tip if you don't already do this: get the paper towel wadding soaking wet, then stuff it down the barrel, if you hear air hissing around it as you push it down then your good. i found this method gets the most veleocity out of your air pressure because the wet paper towel gives it a near perfect seal. try it.

[metalstorm91291]

@Triplegack Great idea, I'll have to try that!

Foghorn goes _before_ the shot, not after.

the honking sound sounds like the tractors in the movie CARS. Very cool video.

@Slavonic707 linkin park

[tjtomax]

optimal dist. is actually 47 degrees when you account for wind resistance

vaporizing random shit in 3-2-1 whoooo

[billhaley1868]

great video

[Trezeverest]

me and my friends made one similar in dimensions, one of ours is combustion, not compression and goes a little further than a half mile with solid marble projectiles

[cmiccy1]

So for the papertowel wads, do you just stuff a bunch down the barrel really tight?

[DtCKclan]

you should mod those sprinkler vales

[MindWarp95]

awesome

Ive made a similar one to that

2 inch dual chambers with a 2 inch 2.5 inch and a golf ball size interchangeable barrels

but on most occasions i only go to 40 psi because i struggle with a hand pump over that

10/10

best air cannon seen

[campbell127]

through previous testing we figured a ballpark distance... vertical shots gave us rough flight time, simple physics equations give you a ballpark distance possible... our shooting range was just over a 1/4 mile, and it coudl have easily doubled that distance...

[B3nNy88]

it shots but i think not 1/2 mile... how can u see and find the golf-ball at that distance?

i had play golf some years and with the drive i can shot to 220meters... while it flies already at 180 that distance u lose the ball-seing.

[firstatv]

am thinking of making one that's something like yours.

[1Paintballer]

Thats so cool, Im planning on building one is it better to use ABS or PVC pipe or does it matter?

[TheShway]

pvc, ive built like 5, and it works great

[ajd2466]

dude that was sick!

[mccarthy4187]

BRILLIANT!

[campbell127]

yeah, the sprinkler solenoid valves vibrate at lower pressures, making the foghorn sound.. a delightful side effect

[ihavenoclue921]

whats that horn sound?

is that the cannon?
