Just fired my potato cannon with 3 seconds of hairspray and my ears are still ringing. That was the most epic moment of my life

Man, my old potato cannon like your “traditional” one was a beast. It sounded like a shotgun going off and would shoot a potato so fast you could barely see it.

2:23, you got your buddy standing downrange, brilliant.

Everyone knows an underground bunker full of potato batteries powering a surface to orbit laser battery is the supreme form of potato gun

You should build a magnetic rail potato gun you probably got most the stuff.

When I saw that chronograph I could not stop laughing 😆

For the grill sparker style I recommend 91% isopropyl alcohol. As long as you give it fresh air between each shot it will go off.

I did a search on different fuels. I found a page claiming the navy did a potato canon study using different fuels. Acetylene gave the most distance

Your velocity is super low. Ive never had a potato bounce off of a target. I get reliable ignition with aqua net, and can blow a hole in 3/8 plywood. Hitting an oak tree will turn the pitato to mist and remove the bark of the tree in an 8" circle. Also, sharpen the outside of your muzzle so you get a perfect cylinder of potato going down the bore

You need to give the size, shape, weight and material of each projectile being fired. Especially for the chronographed ones so you can compare the power or inertia of each projectile. Haven't you seen any gun channels? the good ones even tell you how they load their rounds lol. Also if you want a better ignition source then order a few cheap plasma lighters online, you can attach the leads to some bolts in the chamber and they should last longer but if you epoxy a nut on the inside and one to the outside of the chamber then they become both replaceable and tuneable. When placed properly they can get that extra 5% of capability out of it. Also for using liquids like alcohol or lighter fluid that works best when vaporized, I have found that pre-mixing it in a separate container can be the most reliable method, like pouring rubbing alcohol into a big 3 liter bottle and filling the cannon by squeezing the bottle so that the vapor and air from that is used as fuel, then you don't need to worry about putting too much in there you can just have extra in the bottle and as long as you just use the vapor from the bottle and not the liquid it is already got a great ratio in it!

Gabe: In case you have not done so since making this video, it would IMHO be cool if you reworked the 'acrylic shield' on your Howitzer so your aiming telescope would actually work...👍

What if you designed the combustion chamber like a carburetor where there is a constriction to increase the velocity of the gas where you have the ignition on the back and the other side that connects to the barrel would be 1/3 the length of the high pressure end(the ignition side)

I have a theory that the 1 inch barrel encourages a longer slimmer projectile that will fly truer and tumble a lot less. A 2 inch barrel gives a shorter fatter round [comparatively] for the length of the potato so it is more likely to randomly spin and be inaccurate as it is less aerodynamic.

Nearly got mad because of the flies watching this in earphones

Starting at about 07:00 in this video: You created a SPUDSHEET...😊

Great video. For what it is worth, here is my analysis. We are not trying to kill anything so, the Cool Factor rules.

mmm stereo fly buzzing sounds. thought it was a real fly by my head because I am wearing headphones

You're wrong on the accuracy of the metal canon : it hits something right in the middle : the chronograph :D

We need to know what's the accurate of metal potato gun??!!

Gabe: *_"We also had a pretty cheap chronograph..."_* Which got EVEN CHEAPER before the end of the video...😉

We all love your videos so much!!!!

*HOW MANY POTATO CANNON VIDEOS ON THIS CHANNEL HAVE I MISSED??!!* 🤭🤭🤭

“Send it”

of course when i search or potato cannon, you come up. hahaha.

I know this is an older video but I can tell you from catching spuds fired from the best “357 Spud” gun I built that would shoot spuds consistently over 1200 feet, these things shoot knuckleballs big time! They float all around even at 25 yards (best catching distance). Oh yeah, the spuds do explode in your glove most of the time. 🙂

now you just need to build a hybrid spud gun that uses a preloaded piston to maximise the gas pressure. they are insanely powerfull. make it from steel and load with oxy acetyline plant.

Amazing video. 10/10

I see many potatoe cannon makers shoving potatoes extremely tightly down the barrel for the sake of preventing any air escaping. But dont you hinder the potatoes speed when you shove it that tightly in the barrel? It would seem if your wanted the optimal speed you would cut the potato so it barley touches the sides of the barrel. That would prevent air from escaping, while keeping friction to a minimum.

What if we could add high fuel to air and pump it pneumatic a few times?

I wanna know the classified propellant

Try using Oxy&Acetylene mix

I love how you just smoked your chronograph and act like nada happened, also do you live in a train??

which is more powerful combustion or pneumatic?

My family needs to be friends with your family.

4:40 you can try deodorant like axe, that shit hits

New Glarus, Northern speak, you guys are definitely in the UP

Was the green cannon powered by acetylene or menthonol?

Give’m some juice- too weak

*ok now pierce a tank*

If you put a nice thick layer of grass for a wad, you can use potato salad...

Use bigger russet potatoes and have a section of pipe that you can use to "cookie cutter" the potatoes into reasonably consistent shapes and yall should have very repeatable results withing fairly accurate ranges

6:57

Need to ditch the potatoes and get 1/4 full chalk tube flair the end to fit a 2 inch tube for good seal and you will have distance and vol

Why not try HHO or welding gas?

you should make a side breack simplified, no propane or air compressor like the walmart version

try butane

Are you shooting tennis balls?

Oxy acetylene special formula

Can you launch a potato with a nail-gun blank?

So if you take this hunting, would it actually take down an animal?

90% OF YOUR PROBLEM IS YOUR COICE OF FUEL. BOTH ETHER AND HAIR SPRAY ARE WETTING YOUR ELECTRODES. sorry, caps on. you need a dry fuel for reliability. compressing said "dry fuel"; helps. accuracy should be fairly accurate at 300M-500M. muzle velocity can exceed 100kmph, easily!

Hay

Rifle the pipe and use Aqua Net. You have no accurate guns. That means you hit the target. Yours go opposite of the last part of the potato that comes out. Simple science. The original gun is built wrong entirely.

Dude... Put the camera facing the target from where you're at or somewhere where you can see everything. You couldn't see shit for like 90% of the video.

Im late to the game, but i have a 2 inch barrel with a 6 inch combustion chamber which is pretty stout with a 350 to 400 yard launch but it doesn't hold a flame to another youtuber's design of using schedule 80 pvc with a double combustion chamber, a evacuation fan and a taser's arc for ignition. For ammo he's firing 70mm cans of spray paint. Fkn brutal. also sweet potatoes are dryer which slows in barrel from friction counteract this with a bit of wd-40 or lube. Ive found ether starting fluid, acetone, propane and acetylene as the best fuels
