How fireworks turn to shapes similar to hearts and stars
Briefly illustrate how do fireworks turn to shapes similar to hearts and stars?
Expert
The fireworks creators encompass worked for many decades to figure such things out. There are many factors. The individual little bursts are wrapped individually. They are then arranged about a core in the shape desired and the propellant charge is positioned in the middle. Whenever it goes off it lights the individual bursts and propels them in the desired shape.
