Did you know, behind the brilliant beauty of 'fireworks in the sky' is a feat of manufacturing .
>>>History of birth of fireworks
Images of blooming fireworks in the sky have become so familiar to many of us whenever there are important events. But have you ever wondered how to be able to admire such brilliant fireworks displays, how will the structure of fireworks be?
With his curiosity, photographer Andrew Waits exploited another aspect that the audience rarely paid attention to, which was the appearance of the cannon before the explosion.
The interesting set of photos below can make viewers admire the incredible power behind these tiny detonators.
Fireworks were invented in 200 BC into the Han Dynasty in China. Few people know that the origin of the idea of making fireworks was when the ancients saw the small bamboo tube exploded when thrown into the fire.
Because of that, the shell of fireworks is often made from bamboo pipes, logs or iron shells.
By the thirteenth century, fireworks and gunpowder were actually spread to Europe. While many countries focus on developing gunpowder for war, Italians are interested in studying fireworks.
The structure of modern fireworks consists of 4 main parts: frames, fire particles (star particles), explosion parts and fire conductors.
The frame of the fireworks consists of a braided wire into a round cylinder and paper around it.
Part fire particles are spherical, cubic or cylindrical.
Explosive parts are in the middle of a bullet, usually made of coal, sulfur and potassium nitrate.
The length of the fire conductor will determine the waiting time for the bullet to explode at the correct height.
