As effects, colored smoke is used here as rising columns or colorful balls of smoke in the sky. For close-ups, light batteries are particularly suitable, which eject paper snakes instead of colorful light balls. Or how about a 20m2 flag printed with your company logo or a flying advertising column that slowly floats from the sky to the ground. This is also possible. There is almost no more fancy advertising. For this kind of fireworks the necessary safety distance is relatively small despite the large calibers (210mm), because no burning effects are ejected. Let us advise you without obligation.

safety distance >=50 meters
