Explosives are not playthings. If you insist on putting on your own display, prohibit children from getting near the fireworks. Wear safety glasses and read all instructions. Set a safe example. Repeat instructions and make sure alcohol is not involved.
Alcohol slows reaction times and clouds judgment.
