How Does A Real Cannon Work? 

A cannon works by harnessing the explosive force of gunpowder to propel a projectile, typically a cannonball, with tremendous force. The process begins with loading the cannon’s barrel with the projectile and then adding gunpowder behind it. A fuse or ignition mechanism ignites the gunpowder, causing it to rapidly combust and create a high-pressure gas. This gas builds up behind the projectile, pushing it forward and out of the cannon’s barrel at high velocity. 

The size and shape of the cannonball, as well as the amount and type of gunpowder used, determine the distance and impact of the projectile. Cannons come in various sizes and designs, from handheld cannons to massive siege cannons, but they all operate on the same basic principle of harnessing explosive energy to launch projectiles.
