Key Facts In This Video
Fireworks require two explosions: one to get them up in the air, and another to produce the colorful design. 00:10
When lit by a fuse, gunpowder at the bottom of the firework will explode and propel it into the sky. This also lights a fuse inside the shell, which burns until it reaches maximum altitude, then explodes in color. 00:44
Inside the shell are tiny pea-sized balls that burn rather than explode. Specific chemicals, such as strontium, can make them burn a particular color. 00:58
