hi guys in found a gas that looks like it could really project some stuff real far, but it looks like it could explode in my hand too..
its a composition of 95% butane and 5 % propane ( based on net weight, which is 250g)
mind telling me if its safe for use ?

its fine to use. not the best but id suggest pure propane but some butane will decrease the burn rate making it safer. its good to use.

Yea that, and if it says flammable. Flammable stuff tends to work pretty good...

I know a guy that made a cannon that used all purpose flour and it made a nice muzzle flash. I guess this is by way of saying that anything that will burn can work]

I wonder how he atomised the flour? I wonder if anyone has tried other stuff like coal dust or icing sugar.

Edit: I suppose you could just use a strong fan to blow it all about.

He shakes up the cannon with a little bit of flour in the chamber to get the proper air flour combination.
