What is in a Cherry Bomb?
Cherry bombs, also known as M80s or M100s, are a type of firework that has been a staple of American pyrotechnics for decades. These small, spherical devices are designed to produce a loud, fiery explosion, often used in celebrations, parties, or as a form of amateur pyrotechnics. But have you ever wondered what’s inside a cherry bomb?
Composition of a Cherry Bomb
Before we dive into the nitty-gritty of a cherry bomb’s composition, it’s essential to understand the basic components of an explosive device. A firework like a cherry bomb typically consists of:
• Filling: A pyrotechnic composition that produces the explosion, color, and sound.
• Binder: A binding agent that holds the filling together and adheres it to the casing.
• Casing: The outer shell of the firework, usually made of paper, plastic, or metal.
Now, let’s break down the contents of a cherry bomb specifically:
- Filling: A cherry bomb contains a pyrotechnic composition made of black powder (a mixture of charcoal, sulfur, and potassium nitrate) and stabilizers (such as clay, silica, or alumina) to improve the composition’s burn rate and stability. This mixture is what produces the explosion and shockwave.
- Binder: The binder is typically a mixture of cerium oxide and silica, which adheres the filling to the casing and helps maintain its shape.
- Casing: The casing of a cherry bomb is usually made of paper or plastic, which provides protection and structural integrity.
How Does a Cherry Bomb Work?
So, how does a cherry bomb produce its signature explosion? Here’s a step-by-step explanation:
- Ignition: The cherry bomb is ignited using a fuse or ignition powder, which sets off the pyrotechnic composition.
- Heat Generation: The black powder in the filling begins to burn, generating intense heat and producing a rapid pressure increase.
- Expansion: The heat generated by the burning black powder causes the gases produced during combustion to expand rapidly, creating a shockwave that propels the casing and filling outward.
- Sound and Light Emission: As the pressure wave reaches the atmosphere, it produces a loud explosion and bright flash of light, creating the characteristic burst of a cherry bomb.
- Cooling and Exhaustion: As the pressure wave dissipates, the gases produced by the combustion process cool, and the cherry bomb settles back into its original shape.
Safety Considerations
When handling cherry bombs or any other pyrotechnic devices, safety should be your top priority. Here are some crucial safety considerations to keep in mind:
• Keep a safe distance: Never handle or ignite cherry bombs in enclosed spaces or areas with flammable materials nearby.
• Wear protective gear: Always wear protective eyewear, gloves, and clothing when handling or igniting cherry bombs.
• Follow ignition procedures: Always follow proper ignition procedures, and avoid using ignition sources that are too powerful or unpredictable.

Conclusion
Now that we’ve explored what’s inside a cherry bomb, it’s clear that these small, spherical devices contain a carefully crafted mixture of pyrotechnic components designed to produce a powerful explosion. Whether you’re a pyrotechnic enthusiast or simply looking for a fun and exciting way to celebrate, cherry bombs are an iconic part of American pyrotechnics. Always remember to prioritize safety and follow proper ignition procedures to ensure a thrilling and memorable experience.
