Com: Wrong Wrong : Pro tip: put the flares in a 10 yard diameter circle around the tanks, instead of on them.
That way you get combustion when most of the (heavier than air) gas has leaked out, and a much stronger pyrotechnical effect..
Com: DesertMayhem: You had road flairs on the tanks. What the point of using the silver tip ammo?
Should have used regular AP round. Might have gone through more than 2 tanks.
Com: Fırfır: That wasn't as impressive as I imagined. I used to duct tape blockbusters to cans of starting fluid, it was almost as good.
Just with those 2 items! I believe, if you somehow worked the quarter sticks in w/ the propane tanks, and maybe touch it off w/ the rifle.
Maybe, add more blockbusters you could make something quite a bit more powerful and spectacular
