Manufacture method of double kick shooting artifact

The production method of El Foundation blasting products is as follows:

The practice of putting two kick artifacts can be divided into barrel rubbing, lead making, frying and sawing, frankincense, eye piercing, drug transfer and packaging.

Double-kicking firecrackers are traditional folk products in Jie Zhen, which are often used in festivals, weddings, commemorative ceremonies and many other occasions. It is based on the principle of taking off due to the reaction force generated when the bottom powder explodes and hits the ground. The paper tube with double-kicking firecrackers is divided into two layers. The lower layer of gunpowder is used to send firecrackers to the sky, and the upper layer of gunpowder explodes in the air after taking off 10-20 meters.

The powder for kicking two feet is divided into two layers with cement or soil. The back door at the bottom was not blocked tightly, and the airflow generated by the lower gunpowder explosion slammed the back door and ejected downward. The downward jet of air generates upward thrust, pushing firecrackers into the air.

Matters needing attention in setting off fireworks and firecrackers

First of all, we should choose the right place to set off fireworks. It is strictly forbidden to set off fireworks and firecrackers in busy streets, theaters and other public places, forests, power facilities and places close to flammable and explosive materials. Clear the ignition position, use smoke or incense, and after ignition sideways (no part of the body is allowed to face the direction of the product's discharge trajectory), people will leave to a safe position.

In case of abnormal conditions, such as flameout, never re-ignite, let alone stretch your head and look at it with your eyes, and don't go near the product immediately. Stop discharging other products and wait until the reason is clear, usually 15 minutes later. Fireworks must not be inverted. It is best to use objects or appliances to set off fireworks that spit beads on the ground. If you really need to set off fireworks by hand, you can only hold the end of the barrel with your fingers and don't point the bottom at the palm of your hand. After lighting, straighten your arms and put the fireworks mouth up.
