Synopsis

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A firecracker (also known as a cracker, noise maker, banger, or bunger) is a small explosive device primarily designed to produce a large amount of noise, especially in the form of a loud bang; any visual effect is incidental to this goal. They have fuses, and are wrapped in a heavy paper casing to contain the explosive compound. Firecrackers, along with fireworks, originated in China. Firecrackers are generally made of cardboard or plastic, with black powder as the propellant. This is not always the case, however. Anything from match heads to lighter fluid have been used successfully in making firecrackers. The key to loud firecrackers, however, although in part lying in the propellant substance, is pressure. The entire firecracker must be very tightly packed in order for it to work best.
