Oh, them potato cannons, eh? You young folks always got them fancy ways to have fun. Well, lemme tell ya, if you’re looking for the best fuel for them potato guns, there’s quite a few things folk been tryin’. I ain’t no scientist, but I done heard from folks around here about what gets them potatoes flyin’ far and fast. Now, some might swear by this or that, but I’mma lay it out nice and simple for ya.
First off, let’s talk about some of them fancy fuels. There’s a whole bunch of stuff folks been stickin’ in them cannons. Like, they use hairspray, starter fluid, butane, propane, and even alcohol. Them things sure do make a good bang, but which one’s best? Well, from what I done heard, acetylene is pretty much the top dog if you wanna get that potato movin’. It shoots them taters out at about 138.1 meters per second! That’s fast! Behind that, you got methanol at 48.2 m/s and butane at 34.6 m/s. Then there’s ethanol and propane, which ain’t as fast, but still get the job done, around 33.3 m/s and 27.9 m/s.

But lemme tell ya, it ain’t always about speed. You gotta think about what’s safe too. You don’t wanna go blowin’ yourself up, now do ya? So a lot of folks say that compressed air or nitrogen gas is the way to go. They don’t burn like them other fuels, so they’re safer to use, especially if ya ain’t too keen on setting fires. Plus, they’re easy to get your hands on and work just fine without all that kaboom.
Now, I know some of y’all like to go big, so you might be thinkin’ about startin’ fluid or somethin’ like WD-40. Yeah, them things’ll make a real loud boom, but they ain’t always the most consistent. I heard that starter fluid’s got a mix of stuff in it, like dimethyl ether and propane, and they’re real combustible. But if you use too much or too little, it ain’t gonna fire right. The trick is to get the ratio just right. For some fuels, if you got too much or too little, it won’t burn at all.
Speaking of ratios, now this might sound a little tricky, but bear with me. Some smart folks say if you want your potato gun to work good, you gotta get the ratio of the chamber to the barrel right. They say it’s best if the chamber is about 1.5 times the size of the barrel. That’s called the 1.5:1 ratio, or somethin’ like that. I don’t mess with them numbers much, but if it helps the cannon shoot better, I reckon it’s worth a try.
Safety first, always. When you’re playin’ around with these fuels, remember, it’s dangerous stuff. Don’t go messin’ around without knowin’ what you’re doin’. Folks have hurt themselves pretty bad by not bein’ careful. Make sure you’re out in an open space, and for heaven’s sake, don’t point that thing at nobody. And if you can, try to use stuff like compressed air, like I said earlier. It’s safer, and you won’t have to worry about blowin’ yourself sky high.
Other fuels folks have tried. Some folks get real creative, usin’ stuff like hairspray, which is pretty common. But it ain’t the most reliable. You might get a few good shots, but after that, it starts to fizzle out. I heard folks also use denatured alcohol, but that’s a bit trickier to handle. You gotta make sure you’re usin’ it right, or it ain’t gonna work. Honestly, if you’re new to this, stick with the easy stuff like compressed air or maybe propane if you’re feelin’ a bit adventurous.
So, what’s the best potato cannon fuel? Well, that depends on what you’re lookin’ for. If you wanna shoot far and fast, acetylene is your best bet. But if you’re more about safety and havin’ fun without riskin’ life and limb, compressed air or nitrogen gas might be the way to go. Whatever you choose, just be careful, alright?

- Acetylene – Fastest, but more dangerous.
- Compressed Air/Nitrogen – Safe and easy to get.
- Methanol/Butane/Propane – Decent performance, but not the fastest.
- Hairspray/WD-40 – Fun, but not very reliable.
So there ya have it, now go have some fun shootin’ them taters, but remember to be safe!
