(1) We draw a small circle on the paper. This is the center of the blooming fireworks. Draw small raindrops around this center. This raindrop should be slender. Let it evenly surround the circle just now. Then draw some bigger raindrops in the space between each raindrop, which is just a circle.

(2) Draw some arcs irregularly around the heavy raindrops, and these arcs should have a feeling of falling underground. Draw some dots on the outermost circle of the whole fireworks. Similarly, we draw a simple version of the small fireworks on the right hand side of this fireworks. Finally, we can color these two fireworks. Whether you like bright fireworks or low-key fireworks, everyone is free to decide the color. Let your imagination go.

Fireworks are actually similar in structure to firecrackers, both of which contain black powder and medicine. In order to achieve good performance, fireworks and fireworks bombs are filled with a lot of gunpowder for launching and explosion. For example, a fireworks bomb with a diameter of 20 cm will explode only when it rises to a height of about 200 meters after launch, and the radius covered by these points can be about 80 meters.

After the fireworks are lit, a chemical reaction similar to the above causes an explosion, and most of the energy released during the explosion is converted into light energy. Adding some luminescent coloring agents in the process of making fireworks can make fireworks emit colorful colors.
