If you're having fireworks at your home, you might have a big box of assorted fireworks.
Everyone has their personal favorites and people might have clear ideas of what they want to see and hear. You can play a game to determine who gets to pick the next firework to go off next. You might ask trivia questions (why are there 13 stars on the flag?).
Another idea is to have a dance off. While music plays in the background, each person who really wants to pick the next firework to go off has to dance the craziest, silliest dance they can come up with. Someone who's been designated a judge will decide who won the dance off and that person gets to pick the next fireworks item.
Unless there are more fireworks than people, each person only gets to pick once.
