Do you watch fireworks and wonder how they make all those different shapes and colors in the sky?
00:00:05:01 - 00:00:08:00
Unknown
The secret lies in how the fireworks are packed.
00:00:08:00 - 00:00:14:24
Unknown
Each firework shell is packed with small pellets called stars, and are arranged in specific shapes inside
the shell.
00:00:14:24 - 00:00:18:07
Unknown
When the fireworks launch and explode in the sky,
00:00:18:07 - 00:00:21:12
Unknown
these stars follow the pattern they were arranged in,
00:00:21:12 - 00:00:24:17
Unknown
creating shapes like circles, hearts, or stars.
00:00:24:17 - 00:00:30:08
Unknown
The explosion that propels the stars outward is directed by a bursting charge in the center of the shell.
00:00:30:08 - 00:00:34:24
Unknown
How the stars are arranged around this charge determines their shape in the sky.
00:00:34:24 - 00:00:38:05
Unknown
So if the stars are arranged in a circle around the charge,
00:00:38:05 - 00:00:41:00
Unknown
they will explode outward in a circular pattern.
00:00:41:00 - 00:00:45:01
Unknown
The color of the fireworks comes from different chemicals added to the stars.
00:00:45:03 - 00:00:47:05
Unknown
Strontium produces red
00:00:47:05 - 00:00:51:08
Unknown
barium produces green, and copper produces blue.
00:00:51:08 - 00:00:54:08
Unknown
I’m never watching fireworks the same way again.
