Introduction: How to Make a Potato Cannon (Combustion) Advanced Ep 2 of 2


Here is a tutorial video on how to make a combustion potato cannon from the man behind ..

TheBuG or MushiYoshi. The video shows how i made my standard size potato cannon step by step.

Made in Norway

For more info about this cannon and how to make one, go to and go to the potato cannon link

This is not spam, but a warning. PVC will fail suddenly after a while. This was band member that hurt badly by a T-Shirt launcher explosion.

You seem like the kind of person who knows a thing or two about massive cannons...

What do you think of my idea to build a 12"(diameter) air cannon to shoot ~35 pound water balloons with a muzzle energy of ~184,000 foot-pounds?

does it work better than an air cannon?

marffy (author)voltagedude2009-11-23

 that depends on how u build ur air cannon. I could easily build a stronger cannon then this. The cannon is VERY powerful but there can be more powerful. Depends on how u make ur cannon.

Using explosives is more fun though.

marffy (author)Cobalt592011-01-18

Very true.

FINALLY an ADVANCED combustion cannon on instructables. all the others are lame pill bottle ones that shoot like 10 metres.

entoalexa (author)blugyblug2010-02-07

yea, but YOU'VE made a pill bottle gun

what stops the combustion from burning up the internal mechanisms such as the wires, fans, wood, and pvc

marffy (author)wolfmage3562009-11-23

 The "explosion" inside the chamber just makes pressure not so much heat. This results in no melting and burning of internal parts.

are the "corks" soda bottle caps?

Me and a friend of mine made one of these, with just 4 small puff's of hairspray we launched a energy drink molotov about 100m far away (energydrink molotov: a empty energydrink can, filled with gasoline and then add a small piece of gasoline drenched cloth in the hole, light the cloth and launch it within about 20 secs of lighting it) We did this at an old abandoned mine so we couldn't put anything on fire :) Energydrink cans fitted amazingly into ours ;D, or those mini cola cans, their the same diametre as energy drink cans, but smaller! Ps: We made interchangeable barrels, you could just "unscrew" em like a silencer and change the diameter of the barrel :) we can shoot from marbles to tennis balls ;D

also how much in total did you pay for all materials in the end

thepaul93 (author)2009-06-09

how did you make the spark generator

mrianniello (author)thepaul932009-06-25

i suggest buying a bbq lighter... there 5 dollars but they have the best results

thepaul93 (author)mrianniello2009-06-25

that one was powered by a battery

kollijolbein (author)2009-03-08

this gun is much more advanced than my gun :P Looks badass too

bowhunterhall (author)2008-11-07

what is the fan for i don't get it.

Kaiven (author)bowhunterhall2008-11-28

Circulating air and fuel. Not really needed, but can help.

blugyblug (author)Kaiven2008-12-29

Mixes the fuel and air together so the explosion in the chamber is equal and spreads. Its actually pretty useful.

Kaiven (author)blugyblug2008-12-30

But it's not needed :P

blugyblug (author)Kaiven2008-12-30

Yeah its not vital but it helps.

ChappyShowcase (author)2008-10-17

Dude, your gun is super cool. Way more complicating than mine in my video. Of course, I was going for creating something a general audience could figure out. Kudos again. ChappyShowcase

nibbler125 (author)2008-10-14

i love the hairspray holder idea i will be using that on my next gun for sure

Kaiven (author)2008-10-13

your cannon is very good compared to the one I've made.

thebluemartyr (author)2008-09-23

its amazing, but god way to dam over the top for me. kudos on making a gun that looks like a wmd.
