I love watching the bright blue and orange muzzle flash at night with my combustion. Whats the longest flame you have ever gotten out of your barrel at night? Please post pics if you can :D .

I have a gun that I made before I knew anything about C:B ratios. It is a 2" chamber around 2' long, with a 1" barrel around 2' long. I can get a huge flame out of it using hairspray.

I have never even seen a muzzle flash out of mine. Even at night.

Yeah... at a .8:1 ratio on one of my old guns all I saw were a few sparks from the end of the barrel at night, (probably small potato bits).

I have a 1 foot 4 inch chamber and a 5 foot 1 1/4 inch barrel. I use hair spray but I have never seen a flash. I might have to little amount of fuel. I use about 1 second but it still goes like 200 yards.
