Here are some key characteristics and features of Chakkara firecrackers:

1. Shape and Design: Chakkara firecrackers typically have a circular shape, resembling a small disc or wheel. They are designed to spin rapidly on the ground when ignited.

2. Composition: Chakkara firecrackers are made using a combination of pyrotechnic materials. The exact composition may vary, but it usually includes a mixture of powdered metals, fuels, and oxidizers.

3. Ignition Mechanism: Chakkara firecrackers are ignited by lighting a fuse or a designated ignition point. Once ignited, the firework starts spinning rapidly due to the propulsion created by the expelled gases.

4. Spinning Effect: As the Chakkara firecracker spins, it emits sparks and colorful flames. The rotation creates a circular pattern on the ground, producing a visually appealing effect.

5. Noise Level: Chakkara firecrackers are generally considered to be low-noise fireworks. While they produce some sound due to the combustion process, their main emphasis is on the spinning effect rather than loud bangs or explosions.

6. Variations: Chakkara firecrackers come in various sizes, from small ones that fit in the palm of your hand to larger ones that can have a diameter of several inches. The larger ones typically produce longer-lasting and more pronounced spinning effects.

7. Safety Precautions: When using Chakkara firecrackers, it's crucial to follow proper safety precautions. Ensure that you are in a clear and open outdoor area away from flammable materials. Keep a safe distance from the firework while it is spinning and maintain adult supervision, especially when children are present.
