What’s that in the sky? Is it a bird? Is it a plane? No, it’s a firework! Fireworks capture the attention of crowds around the world, but how do they work? First, the firework is stuffed into a tube loaded with gunpowder. This is the mortar. Second, a fuse that leads to the mortar is lit. When the fuse ignites the gunpowder in the mortar, an explosion launches the firework into the air. A fuse on the firework is lit at the same time as the mortar fuse, but this fuse burns slower, allowing the firework to get into the air before it explodes. After it has risen to its peak, the firework should explode, causing tiny pieces of metal to burn in different colors as they scatter outward. Oooooh! HELPPP
