This is the shocking moment a young man deliberately threw a firecracker down an underground septic tank in a Chinese residential complex, causing it to explode.
The huge blast sent a 110lb manhole cover flying some 10 feet into the air, according to Chinese media.
The heavily manhole nearly hit one of three men, who were playing with firecrackers, as it landed just one feet away from him.

The firecracker lit the colourless gas methane in the septic system, which led to the explosion.
It’s understood no one was injured by the incident, which happened in southern China’s Hunan Province on February 18, reported local Changsha Evening News.
The residential complex has 168 households that share one septic tank, management told a local reporter.
No injuries have been reported.
The young man, who remains unidentified, had ignited one of the tank’s four access points.

As stated by the report, the trio knew each other. They were visiting relatives during the Lunar New Year celebrations. The bored friends decided to have some fun by igniting biogas in the area’s septic tank
CCTV footage circulating on Chinese social media shows them backing away after dropping the firework down the manhole, and seconds later the ground erupts in a cloud of dust and smoke.
It is unclear whether the teenagers received any punishment.
Authorities have warned against the dangerous game, especially during Chinese New Year holidays when young children often have access to fireworks.
Just last month a boy seriously injured himself after throwing a banger down a manhole and being launched some 10 feet into the air by the resulting blast.
