If you want to buy powerful fireworks and firecrackers that exceed the standard, you can't buy them through formal channels, but the wholesale market in the urban-rural fringe is different. A store owner said that in order to cope with the inspection, ordinary fireworks and firecrackers were put in the store, and the really powerful products were hidden in the warehouse. These are also very popular varieties in rural markets. Seeing that we are sincere, the shopkeeper pulled a box to open our eyes. According to the loading amount of explosives, fireworks and firecrackers are divided into four grades of ABCD. A-class fireworks bomb, also known as A-class fireworks bomb, has a diameter of more than 72 mm;
Class B fireworks include fireworks with a single charge of more than 40 grams, large firecrackers with a charge of more than 8 grams, fireworks, fireworks bombs and small fireworks with a charge of more than 2 grams. Because of its great power, Class A and Class B fireworks are forbidden to be set off, and must be set off by professionals.
The high-altitude fireworks bomb that the shopkeeper took out, although not marked with grade, belongs to A-class products. In the wholesale market, there are many illegal products similar to fireworks bombs, and some merchants even mark Class A fireworks as Class B or Class C for sale. Curious Lab bought several models at random to see how powerful they are. The experimental site is in an abandoned mine, surrounded by no one, and it is also the place where illegal fireworks and firecrackers are destroyed in Hangzhou. The first thing to test is this A-class fireworks bomb. Because the fireworks and firecrackers were not marked with which side was facing down, the experimenter mistakenly turned them upside down, which led to the explosion of fireworks and firecrackers in the gun barrel, which is also a mistake that the fireworks and firecrackers are easy to make. Replace the launcher with an iron bucket, and this fireworks bomb actually blew up the bucket!
Switch to a washing machine bucket and blow it up.
In addition to fireworks, firecrackers such as kicking feet and flying mice will be bought during the Chinese New Year. In theory, firecrackers are not as powerful as fireworks, but if they are set off improperly, the consequences will be very serious. For example, in a glass jar.
The glass jar was blown to pieces, and the debris punctured the umbrella, which was obviously much worse than the normal discharge. Children's favorite flying squirrel firecrackers are characterized by scurrying around in the crowd, which is a big hidden danger to children's safety. We tried. Ordinary fat mice blow the dummy's head and blow it off directly.
