How fireworks work #Fireworks #facts #science
Transcript
00:00When you light a firework, the flame ignites a fuse that goes up into the canister.
00:05This flame reaches a black powder that combusts,
00:09and this propels the shell of the firework upwards.
00:13As it's flying, another fuse slowly burns at a delayed and steady rate,
00:18and once it's high in the sky, the flame reaches the center of the shell,
00:23setting off the second explosion.
