The bright sparkles in fireworks come from burning small bits of metal, such as iron or steel filings.
The fuse sets off a charge, which ignites the gunpowder
. This propels the firework into the sky. Once the firework is in the sky, the gunpowder within the firework ignites.
How are fireworks fired?
The explosion of a firework happens in two steps:
The aerial shell is shot into the air, and then it explodes in the air, many feet above the ground
. To propel the aerial shell into the air, the shell is placed inside a tube, called a mortar, which is often partially buried in sand or dirt.

the spectacular effects are orchestrated by a network of explosives, wires, firing cues and a computer
. Fireworks can also be ignited by a microchip activated remotely.

How are fireworks displays controlled?
The e-matches are triggered remotely from controllers called electronic firing panels
, which have banks of switches assigned either to individual pyrotechnics or batches to be fired simultaneously. The more advanced panels run automatically from computer code.
Why do fireworks designers use computers?
Where fireworks displays of old were ignited by using flaming torches, today’s displays are fired electrically from a safe distance. And the choreography is often handled by a computer, which
delivers firing cues with split-second precision in time with music
.
How do fireworks work?
The sulfur flows over the potassium nitrate and charcoal, which then burn. This combustion reaction quickly produces a large amount of energy and gas – in other words, an explosion. If there is a small hole for the gas to escape, the reaction launches the firework into the air.

take and complete the PGI DOC (Display Operators’ Course) and/or attend an annual training at a fireworks display company near you
.
What temperature do fireworks ignite?

more than 1,200 degrees Fahrenheit
, which is hot enough to cause third-degree burns. The Fourth of July is drawing near and barbeque preparations are underway.
Why do the fireworks give off colors when heated?
The Color of Fireworks
The bright, colorful part of the fireworks display is
caused by “excited” electrons in the atoms of different metal and salt compounds
. These compounds are in little balls called stars, made of a similar compound to what makes a sparkler work. Different metals burn in different colors.
What are the fireworks that explode in the sky called?
A skyrocket
is a type of firework that uses a solid-fuel rocket to rise quickly into the sky; a bottle rocket is a small skyrocket. At the apex of its ascent, it is usual for a variety of effects (stars, bangs, crackles, etc.) to be emitted.
