To create special shapes in the sky, each cannon is crafted into different parts.

The explosive is tightly packed into the paper case. The first part of the cannon will contain propellant to send the cannon into the air. When the propellant burns out, the fire will begin to spread to the slow-burning fuse to detonate the main potion. When the main explosive detonates, the explosives shaped inside will be pushed away, then exploded.

Each dynamite is made in a different way. Then they will be shaped inside each cannon so that each cannon explodes will have many different colors and shapes. The size of the fireworks when exploding in the air will be determined by the size of the explosive. And the shape of the fireworks in the sky is determined by the proportion of explosives.

Fireworks are usually fired on important occasions, it can be fired individually or in scaffolds.
