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

Sparking Effects

Iron

Titanium

Antimony

Phosphorous

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
