There is a new science, a new type of fireworks called Proximate Pyrotechnics. They are closer, but the audience is even safer than when sitting way back at a regular fireworks display. Or bring the display indoors, right inside the arena or stadium or even the local shopping mall or convention center. It works for Disney. You can use fireworks to get people to come to an event, and then to stay until it's over.
Proximate pyrotechnics are more than just mini fireworks displays.
They can be used anytime a bang, a flash, some beautiful colors are needed near people.
