Who doesn’t love a little science? When it comes to fireworks, it’s all about preparation, wiring, chemical reactions, and other special scientific tricks that make those beauties fly and burn bright. Here are some technical facts about the magic of fireworks.
How are they made?
Multi-break shells consist of more than one chamber, separated by cardboard disks and ignited by time fuses. Each chamber has its own bursting charge that lights and throws out the stars. The container must burst open with tremendous force and the longer shell can resist the explosion, the bigger the display will be.
How are they wired?
Every fireworks need is an electrical charge to ignite a fuse that fires another lift charge. This reaction blows the shell out of its steel pipe anchored in the sand. The blast also lights a time fuse at the shell’s base.
How are they launched?
Six to 12-inch shells are fired from trailers filled with sand, which supports 35-pound steel mortars that hold the shells. The shells are fired using a computer that has been programmed with a choreographed firing sequence. The results are nothing less than spectacular!
