The one's you put in a tube and they shoot up about a 100 foot and they light up the sky, I think they are called grenade launchers, You get about 6 in a pack.
they are prohibited in my town and in adjacent towns. we sometimes buy them in nearby towns that permit them, drive into another nearby town that permits them and then shoot them off in some large vacant parking lot. woohoo!
I think fireworks are illegal that shoot up higher then 10 feet in the air in Oregon. I'm old enough to buy fireworks this year though because you have to be 16 to buy fireworks here.
usually i get a box or two of them and light them off at a bonfire lol
