As the Spring Festival approaches, the app Rednote has seen many users use fireworks to ignite flour, some of which have received tens of thousands of likes. A user even shared a tutorial, saying, "The size of the explosion depends on how much flour is used."
At the experimental site, firefighters prepped 2.5kg of flour, with a small double-cracker firework in the center. 3 seconds post ignition, firework exploded, spreading fire to surrounding flour. Dust explosion led to flames up to 5m, igniting nearby flammable materials, causing a large blaze. ignition /ɪɡˈnɪʃn/：点燃 flammable /ˈflæməb(ə)l/：易燃的
Firefighters said that some netizens find such explosions entertaining, but in reality, this behavior carries significant risks. The temperatures generated by a dust explosion are extremely high and can easily cause severe burns to the body while igniting surrounding flammable materials. If the behavior results in property damage but does not constitute a crime, individuals involved could face administrative detention for 10-15 days. If it constitutes a crime, the penalty could range from 3-10 years of imprisonment. constitute /ˈkɒnstɪtjuːt/ 构成 imprisonment /ɪmˈprɪznmənt/ 监禁
At a wedding in Zhumadian, Henan province on April 23, 2021, villagers scattered flour as a symbolic gesture wishing the newly-married couple a long and happy life forever. However, the flour was ignited by fireworks, triggering a violent dust explosion.
