Here are some numbers to give weight to those warnings. A brand new study shows an estimated 85,000 fireworks related injuries were treated in emergency rooms between 1990 and 2003, all involving kids under age 19. Most of those patients were 11 year old boys. As far as what fireworks are legal in our state? Sparklers, fountains, smoke devices, snake and glow worms, trick noisemakers, and toy pistol caps are okay. State law specifically prohibits explosive or aerial fireworks, roman candles, and rockets or similar devices.
