Ertui, or double-ring firecrackers, is a traditional folk product in Jie Zhen, which is often used in festivals, weddings, memorial ceremonies and other occasions. It is a primitive bacteria-catching mechanism that takes off depending on the reaction force generated by the impact force on the ground when the bottom gunpowder explodes: the paper tube of double-ring firecrackers is divided into two layers, the lower gunpowder is used to send firecrackers to the sky, and the upper gunpowder explodes in the air after taking off 10~20 meters.
Erguotou is a kind of firecrackers, and its powder is divided into two layers by cement or soil. The "back door" at the bottom was not blocked tightly, and the airflow generated by the lower gunpowder explosion "pinged" through the back door and sprayed downward. The downward jet of air generates upward thrust, pushing firecrackers into the air. At this time, the fuse just ignited the gunpowder sealed at the upper end, and it quickly burned-exploded, and the second kick blossomed in mid-air. Fireworks also rely on the rapid combustion of gunpowder-the thrust generated by the explosion.
