How To Make Alcohol Rockets From Soda Bottles

It isn't firing. The gun is made correct and the spark is there, just when we add the alcohol infused bottle, it doesn't fire. What am I doing wrong?

Thx bro nice vid

Time to make DIY Artillery...

Wat a cool video. Clear step bij step explanation. You made it easy to make it just by following your instructions. Do you think it is possible to use methylated spirit / industrial alcohol instead of rubbing alcohol?

I'm converting my CR90 Anti Tank rocket launcher into this! Wish me luck! 😍

How much did it cost for both this and the casing.

How far does this rocket launch go?

So I did everything and when I put the bottle on the PVC pipe nothing happened i made sure to get the excess out the the bottle and it still does not work people please help me

You can also just spray alcohol inside the bottle

This video got me into alot of shit

Something along the lines of a Spigot Mortar.

I added some homage fins and it went way higher

When I was a kid, we used to make tennis ball canons. They were tin beer and coke cans, 3 with the bottoms and tops cut off and one at the bottom with top and bottom still on it, all taped together. The bottom can had a small hole about an inch from the bottom. The hard part was carburating the lighter fluid and air just right. Kids assume that the more lighter fluid, the bigger the boom. That's not the case. And I figured out by accident the best way to carburate it. Just a squirt down the top, then one good swing holding the bottom with the top outwards, them shoving the tennis ball in right after swinging it. Light it at the bottom hole. DO NOT USE GASOLINE. USE ZIPPO LIGHTER FLUID ONLY. DO NOT POINT IT AT ANYONE.

I've had some trouble getting consistent ignition. Even 70% worked fine, and then it stopped working without 95%, and then even that wasn't working so well. I think my piezo might be wearing out?! It's extracted from a pocket lighter. (Need to get a grill lighter to see if that works better.)

I may have also been having capacitive coupling issues when I was using an old telephone cord (4p2c) for the two wires for the igniter. Interesting failure mode, but not the complete picture.

Lastly, I've been trying this with a 1L water bottle. Very thin-walled, might be at mild risk of rupture. But I think it also isn't as *rigid*, which might dampen some of the force transfer. Will try to find a soda bottle...

One curious thing I had happen—I launched a bottle horizontally across the yard as a test, with a chain link fence as backstop. When I picked up the bottle, it had a ton of dirt in it! I think this is because the gases cooled and contracted around the same time the bottle bounced off the ground, so it sucked in dirt. This makes me wonder if it also pulls in enough oxygen again for the next launch.

... ok, mine's not working. Old alcohol maybe? I don't have any insulation showing from wires in the glue either, not that I see this making a difference. It worked with some lighter fluid but obviously, this is much more volatile than the alcohol it seems, it melted the plastic bottle a bit but was loud and shot pretty high (fired it straight up) in the air. Thoughts? I'm taking all safety measures in the process and I'm going to do a Polish cannon like we used to do when we were kids, they were pretty loud as I recall. And no, I'm not taking retirement very well.

Can we use like 40% alcohol hand sanitizer instead of the isopropyl alcohol

Have you tried using starting fluid as fuel?

How far does in propel the bottle?

Who else modded this, so it could be a shoulder mounted rocket launcher.

Also it looks great to make it a homemade Panzerfaüst bottle launcher instead!

Cnr get my stuff to launch.... Alot of fuel, a little fuel, shaking blowing into it, using a fine mist sprayer to atomize fuel. Nothing using 70%
Thou will go off.if I put a regular lighter to the bottles end

Excellent idea that makes the little ones happy and creative, as well as the big ones.
Please, which Push Button Barbecue Igniter did you use? I'm asking so I don't buy by mistake from ebay.

Would it be good to add fins to the projectile?

Sir, I am trying to find the bbq ignition you used for this project. Was this a weber bbq igniter? I have decided to use the bbq ignition instead of alcohol or anything like that. If possible, could you send a link? I would greatly appreciate it.

Thank you for answering.

Every time I tried it the white gas just formed and it did not move any reason why.

is this possible using a lighter igniter?

Awesome! I can't wait to try this!

What kind of soldering gun is that? It looks, interesting

It doesn't even shoot straight

I need this

Can I also shoot 500ml bottles ? Yes right haha ? I’m gone build a at4

can you tell this project advantage and disadvantage

i have a project coming up on this halloween its an egg drop and after trying water rockets,airplanes and other various types. I've concluded this is the best, I need to know the specific igniter because the ones i'm seeing aren't the same. If u have a link can you please give it to me.
thanks

If you don’t have wires you can also use a long fuse that you light and wait for it to reach the bottle

Love it! I’m going to show my daughter this.

Play say spark plug and there and hook it to a lawn mower.

Pour in a teaspoon of gas ⛽; everclear sounds better.

I tried this but put flights on the rocket and it flies WAYY farther. Probably 200 feet. 👍

He is currently telling us how to make a small mobile artillery with blunt rounds

Gonna have to try this with my son

Artillery on a budget.

Make it rpg

What bottles did you use for this? The ones I have are all either too small or big. And what size fitting?

thank you so much i did it. ive tried making a potato cannon in the past but could never get the ignition right consistantly but this ignition stick works like a charm! you've got a great yt channel by the way!

I'm gonna make a version of that that is shoulder launched

What gauge wire is that?

Can someone explain it will not work for me and I need it for my Science, fair project

Can anyone help me find one of these bbq igniters? Can’t find any on Amazon :(
