Fireworks Sounds
Narrow tubes of fireworks create pressure that releases a long, high-pitched noise
Short,thick tubes make blunt, deep sounds

Electron StatesElectrons begin at ground state
As the firework explodes the electrons jump to excited state
When the electrons are jump back down from the excited state back to ground state the electrons emit light

Dangers
Fireworks are very unpredictable
Chemicals can be exposed to someone during explosions
Also, fire can be a hazard http://w8themes.com/w

Pollution
Gases are released from explosion and can be deadly to humans if consumed
Carbon Monoxide and Particular Matter are hazardous to the environment
These gases are creating large holes on the ozone layer
