Gunpowder is a type of propellant used in firearms. It is made from a mixture of potassium nitrate, charcoal, and sulfur. When ignited, gunpowder burns rapidly, producing large volumes of gas that propel the projectile out of the firearm.
Gunpowder has been used for centuries in warfare and hunting. It is also used in fireworks and other pyrotechnic devices. Gunpowder is a powerful explosive, and it is important to handle it with care. It should always be stored in a cool, dry place, and it should never be ignited near flammable materials.
