Hey Olaf here, was just thinking wouldn't fireworks be a great idea? like small grenades but with a burning fuse they just stay on the ground and explode after 3 secs (causing almost no radius player/brick damage)
maby a lighter animation?
And how about a some air fireworks, you just put the rocket in the bottle and light it, the model will stay there for about 4 seconds and after that it shoots a projectile in the air, removing the model? (a little more damage to players/brick if the projectile might hit something)
