Before a firework explodes, it is typically referred to as a "shell." A shell is a type of aerial firework that contains explosive materials and is designed to be launched into the air, where it detonates to create colorful displays. The shell is often encased in a cylindrical container and is ignited via a fuse.

What forces are involved during the flight of a firework?
During the flight of a firework, three primary forces are at play: thrust, gravity, and drag. Thrust is generated by the combustion of rocket propellant, propelling the firework upwards. Gravity acts downward, pulling the firework toward the ground, while drag, caused by air resistance, opposes the upward motion. The interplay of these forces determines the firework's trajectory and height before it explodes in the sky.

How do pyrotechnicians control the timing so that the firework doesn't explode until it is 500 feet in the sky?
Pyrotechnicians use a combination of fuse lengths and electronic ignition systems to control the timing of a firework’s explosion. They calculate the burn rate of the fuse, which allows them to determine how long it takes for the firework to reach a certain altitude before detonating. By adjusting the fuse length or programming the electronic ignition, they ensure that the firework reaches approximately 500 feet before the charge ignites and explodes. This precise timing is crucial for safety and visual effect.
What is the bottom of a firework called?
The bottom of a firework is called the base or bottom plug, where the fuse is typically located and ignited to start the firework display.
What is a failed firework called?
A failed firework is often called a "dud" because it did not ignite or explode as intended.
If you use feet how high can a firework go before it explodes?
It depends on the firework. Like a bottle rocket can go up to 100 feet but a mortar or shells can go up to300 feet or height depending on the amount of thrust it has and the size of the firework.

What energy transformations take place when a firework explodes?
When a firework explodes, chemical potential energy in the explosive material is converted into thermal energy and light energy, resulting in an explosion and the formation of colorful lights. Some of the energy is also transferred to sound energy in the form of the loud bang you hear during the explosion.
How can you draw an energy transfer diagram for a firework?
To draw an energy transfer diagram for a firework, you can start with the chemical energy stored in the firework chemicals. When the firework is ignited, this chemical energy is converted into thermal (heat) energy, light energy, sound energy, and kinetic energy as the firework launches and explodes. Each arrow in the diagram represents the flow of energy from one form to another.
What is a star called right before it explodes?
Normally it is known as the supernova's progenitor star.
What is the bottom of a firework called?
The bottom of a firework is called the base or bottom plug, where the fuse is typically located and ignited to start the firework display.
What happens when you put potasium in water?
umm, how to explain, it explodes, like a firework but not that high, it can stain a ceiling (I did this experiment in school, well my teacher did)
What is a failed firework called?
A failed firework is often called a "dud" because it did not ignite or explode as intended.
What makes a fire work pink?
A pink firework is usually achieved by using strontium compounds in the composition. Strontium salts produce a pink color when they ignite and burn. By incorporating these compounds into the firework formula, it creates the desired pink hue when the firework explodes in the sky.
Is a firework a source of light?
Yes, a firework is a source of light that is produced through the chemical reactions taking place within the firework materials. When ignited, fireworks emit colorful lights through the combustion of various compounds.
