Firecrackers are a small explosive device designed to produce a large amount of noise, especially in the form of a large bang. Firecrackers come individually and in strips with the strips ranging from 16 – 16,000 firecrackers. Individual firecrackers can range in size which determines how loud the bang will be. Larger individual firecrackers are often referred to as M-50’s, M-80’s, M-1000’s, and a variety of other names. When a strip is lit the firecrackers go in succession to produce multiple bangs. The time of strips can range from 3 seconds to 2 minutes. Many times, firecrackers come in half bricks, which include 40 strips of 16 firecrackers, and full bricks, which include 80 strips of 16 firecrackers. Other types of firecrackers include ladyfingers and jumping jacks.
