In any form of firecrackers, fire is necessary to fire them. If the product is of a wick type, then a wick enters into contact with the fire. According to the moderator, which is a special chemical compound that gives the blasting time to throw away the firecracker, the fire is transferred to the pyrotechnic component of the product itself (magnesium and potassium perchlorate). Located below the photo of the firecrackers "Corsair" gives an idea of their general appearance and design features.

The explosion occurs due to the excess pressure formed in the body of the firecracker, which appears as a result of the burning of magnesium and potassium. Passing fire on the moderator takes a few seconds. During this time you need to have time to throw away the lighted firecracker. The retarder is intended for the safety of consumers of pyrotechnic products.
