We were sure that when a car ran over them the driver would think their tire had popped or something. Now that I'm a driver, I realize we didn't fool anyone. There are other views about fireworks. Some people are allergic to smoke. Those with asthma can get sick from the smoke.
Fireworks are a dangerous way to have fun.
They are not toys, although many who burn them don't seem to realize this. They make dares as to who can hold onto a lit firecracker longest, releasing it just before it explodes. They try to get the biggest bang possible by building bombs with the explosive powder. In the process, many suffer burns every year. In the worst cases, people have lost eyes and fingers.
