 The 4th of July is tomorrow, and with high temperatures and high fire danger across the state, it's important to know that any firework that leaves the ground or explodes in the air is illegal in Colorado. Other laws around fireworks and sparklers vary across counties and municipalities, but you should be aware of your local laws. And always take precautions like having a water bucket or hose nearby. Some popular alternatives to fireworks emerging in recent years are glow sticks, light shows, and drone shows.
