we need another test - and it is about the amount of air - and also the amount of fuel - you known !?! Make it well made - must show what diference for each one of these situations - [few-air+alot-fuel] - [few-fuel+few-air] - [alot-air+few-fuel] - [alot-air+alot-fuel] AND- WHAT ABOUT GASOLINE ? PERFORMANCE - What of them shots more powerfull ? power of each fuel for the pvc spark lighter guns And about the container to barrel hole where the gas gets it's first contact with projectyle - do you known about ? The hole to be smaller is bether or to be bigger is bether ? Power - and what other thing could us want about it performance than power ?
The propane doesn't work because it's a heavier gas and since you held the potato gun upside down it all flowed out the barrel and went outside. You need to put something in the barrel even a lot of Kleenex or something to keep the gas in the chamber.
This brings me down memory lane. This was the warmup for my high school marching band from 8th to 12th grade. Now I’m in graduate school for music Education and Will hopefully be a marching band director next year.
considering this video was over 10 years ao i ll jus sy go to my channel the KEEFeNESS. going to try something much different and all our other awesome videos
Propane with a torch head u need to spray for 30 seconds...its mixing with air so very small amount is getting in there. If u just push the propane valve down with a nail and blast it in there one short burst then scoop 3 4 times with air from your cap. Butane and works best for me one quick short spray.
