Among the wide variety of fireworks, firecrackers deserve special attention from amateurs. Their appearance is familiar to anyone who has ever encountered pyrotechnic products. Being a classic of the genre, of all groups of devices for fireworks, firecrackers are the most popular. In a wide range of products on the pyrotechnics market, firecrackers "Korsar" have proven themselves especially highly.
What is the product?
Corsair firecrackers are small pyrotechnic devices that are convenient to use at any holiday or celebration. The name “petard” comes from the French word ropeter, which means “breaks with a bang.”
What are the types of firecrackers?
Depending on the method of ignition and their design, the following types of firecrackers are distinguished:
- Grating. They are ignited by friction against a matchbox.("Corsair-4").
Wick. For their ignition there is a special igniter cord. ("Corsair-8")
Depending on the reproduced effect, Corsair firecrackers are divided into two types:
- Ordinary. They consist of a cardboard sleeve stuffed with a pyrotechnic mixture. Simple firecrackers are characterized by a bright flash and a very loud bang. There are no other explosion effects.
- Combined, or composite. The explosion of a firecracker is accompanied, in addition to the standard flash and clap, with additional effects: rotation, whistle, emission of multi-colored sparks and smoke. The tearing process is carried out in several series. After the head of the firecracker is ignited, the pyrotechnic means begins to move in disorder. Then, after a shrill whistle, the explosion itself occurs. Those who seek to achieve such effects are advised to purchase Corsair-12 firecrackers. The use of products of this series will add brightness to any holiday.

Composition of firecrackers "Corsair"
The paper sleeve of the firecracker is stuffed with a pyrotechnic mixture, for whichpowdered magnesium and potassium perchlorate are used. These chemicals, when burned, are capable of generating high pressure, which is necessary in order to break the cardboard shell. The process ends with a loud bang. In any kind of firecrackers, fire is needed to launch them. If the product is of the wick type, then the wick comes into contact with the fire. According to the moderator, which is a special chemical composition that gives the blower time to throw off the firecracker, the fire is already transferred to the pyrotechnic component of the product itself (magnesium and potassium perchlorate). The photo of Corsair firecrackers below gives an idea of their general appearance and design features.
The explosion occurs due to the overpressure formed in the body of the firecracker, which appears as a result of the combustion of magnesium and potassium. The passage of fire through the moderator takes several seconds. During this time, you need to have time to discard the lit firecracker. The retarder is intended for the safety of consumers of pyrotechnic products.
Making firecrackers at home
Many craftsmen, having free time, often wonder how to make a firecracker "Corsair" on their own?
Before you get started, you need to get the following materials:
- Ballpoint pen with paste.
- Lighter.
- Two pieces of paper. A firecracker and a wick for it will later be made from it.
- Pack of Corsair-1 firecrackers. Due to its low price, this type is very popular among manyconsumers. One package contains 60 grater firecrackers. They are in the form of sticks 40 mm long.
- Scotch.
- With PVA glue.
To make the process of making pyrotechnics intensive, it is recommended to do all the work in stages.
Steps
Make two cases for firecrackers and wicks. This can be done with a ballpoint pen, on which two prepared pieces of paper are wound. The diameter of the firecracker body can be any. It all depends on the amount of pyrotechnic substance.
Fix the paper wound on a ballpoint pen with PVA glue. The work should be done in such a way that the bottom is at one end of the firecracker.
Wrap the prepared blank with tape. This will prevent the structure from sticking.
Fill the created firecracker with pyrotechnic substance. It can be taken from ready-made Corsair-1 branded products.
Use ballpoint pen and paper paste to make a wick. The work is done in the same way as the body of the firecracker.
Connect the wick with a handicraft firework. For reliability, it is desirable to use adhesive tape.
Nuances at work
The pyrotechnic substance contained in firecrackers ("Corsair-1") is recommended to be kept separately from the fuse, which looks like a pink powder.
When stuffing the body of an artisanal firecracker, only the substance that is removed from the branded firecracker should be used. Pink firing powder cannot be poured into the body of a homemade firecracker. It is only used for stuffing the wick.
Stuffing firecrackers with pyrotechnic substance should be done gradually. After a small amount of powder is poured into the body, tamping should be performed. This is necessary so that the created firecracker does not become a sparkler when it explodes: when ignited, it should explode with a loud pop, and not spark.
When using pink powder for filling the wick, it is very important to compress everything. The better the igniter is rammed, the longer the fuse will burn, which means that the one who detonates the firecracker is more likely to run away.
Safety rules
When using any pyrotechnics, safety precautions must be followed:
- Explosion radius is up to ten meters. Therefore, Corsair firecrackers should be blown up in an open area specially prepared for this purpose.
- If the firecracker suddenly did not work, you can not immediately approach it. You can do this after twenty minutes. Most likely, the unexploded product will be defective. However, it is recommended to fill it with water.
