If you are interested in options to fireworks, the internet is full of suggestions.   Some of the ones we found:

• Stock up on glow sticks, glow in the dark body paint, electric lanterns and balloons and host a glow in the dark party. Black lights would add to the glow.
•  Try watching the stars or organize an outdoor movie (weather permitting).
•   A stunt kite show at night with some LED's (if you have wind).
•  Indoor fireworks projectors are small devices that can be used indoors that produce convincing reproductions of firework displays as well as simulating the noise of real fireworks.
•   Electronic fireworks display lamps produce colorful explosions of light all night long.
•  Home laser shows for the DIY.
•  Community drum circles.
