How to Make a combustive fire shooting potato cannon
Click on Part 2 for the whole tutorial!
Norway's The Monkey Base demonstrates how to make a standard size potato cannon step by step. This potato cannon has the capability to shoot insane fire balls.
Speed and distance : of the potato is 600km/h and it shoots ca 200m.
Spark igniter : search ebay for "electronic spark igniter" sold by sterling products.
Fan : the chamber fan can be used for 2 things. the most importiant is ventilating your combustion chamber after each shot so you get fresh air into the chamber before stuffing a potato down the barrel.
Next is to mix the gas inside the chamber once you have sprayed your combustion gas inside the chamber (I never do this but its always a option).
2 Ventilation holes : the reason I made 2 holes is because if the mixture of the gas does not ignite, or something is wrong, I can ventilate the chamber with something stuffed down the barrel. Kinda hard to put new air into a chamber that is sealed in one end.
3 x Spark patent : The metal\plastic things i attach to the wires is called cable shoes or cable rings, i`ve seen it been used on car electrics.
