Pyrotechnic devices are tools that create visual and auditory effects through controlled chemical reactions. Commonly used in celebrations, such as fireworks displays, these devices produce bright colors, loud sounds, and various shapes. They are designed to burn rapidly, releasing energy in the form of light and sound. These devices can also be found in safety applications, such as flares for signaling emergencies or in theatrical productions to enhance performances. Pyrotechnics require careful handling and adherence to safety regulations to prevent accidents and ensure proper use.
