One time, I drove my scooter (honda) over to a neighbor's bonfire. Some had the wise idea to drop 2 "morters" as we call them down the tube, and light them both. Surprise, one just blew up on the ground, about 15' away from my scooter. And it was a big one. I then moved my scooter.
New Year's Eve I felt like I was doing such a redneck thing-
I had an empty bottle, a gross of bottle rockets, and I was aiming bottle rockets at things.
I shot one in a big bonfire, and much to my surprise, it came back at me, and blew up by my right foot.
Then I decided to shoot them at a tree. Watch them get stuck in the branches. I was about 50 yards from a 55 gal drum (burning barrel), and I almost hit the barrel with the bottle rockets. I was like 3' from it. Pretty accurate, IMO, for a bottle rocket.
We never really get anything bigger than bottle rockets and firecrackers. Too much money. $10 for a gross of bottle rockets, and some firecrackers, and that's all the fireworks I need.
