Fireworks
Fireworks are a spectacular sight. The mod “Fireworks” replaces certain elements in the game with fireworks. This is truly an amazing addition to the world of Minecraft Pocket Edition, perfect for celebrating any occasion, whether it’s New Year or something else. Fireworks feature stunning custom sounds and beautiful visual effects in MCPE.
You can obtain fireworks for free in the world of Minecraft PE from firework vendors (who replace villagers). You can also access items using the creative mode inventory.

Let’s take a look at some of these items. Here we have the wavy firework launcher (bow and arrows). It’s best not to use it at full power, as the arrow will fly too far. It needs to hit an obstacle in MCPE, like the ground or a mountain wall, to explode. 
The rainbow bomb is a slow firework. It takes about 5-10 seconds to explode, but it is undoubtedly the most impressive firework among those available.
However, since it explodes on the ground, you need to ensure that it is far away from you, as it can cause significant damage in Minecraft Pocket Edition.
The standard firework rocket creates some basic explosions. However, it pairs well with others mentioned if you want to create an epic fireworks display.
You can either use each firework individually or combine them all into one epic firework show, just like I did in the video below.
