A video has shown the really shocking moment a young boy was blasted some 10 feet into the air after throwing a lit firecracker down a sewer.
The surveillance camera footage showed how the sewer suddenly exploded hitting the boy by strong force.
Onlookers were shocked when the explosion occurred on a busy street in China.
According to ifeng.com, the boy had lit up the methane in the sewer which caused the accident.
The colourless gas reacted with ignition and caused a combustion that sent the boy some three metres high (10 feet) into the air.
A few onlookers can be seen walking past, as the clip showed.
The young boy, whose details have not been revealed, appeared to be lighting a firecracker near the manhole.
Another young boy came by to watch and seconds later, the explosion occurred.
The sewage cover was left open on the road as other onlookers watched.
The report didn't mention if the boy has survived, or if he has suffered any serious injuries.
It's also not known where the incident took place, but the clip was posted on Weibo to remind web users to be careful during Chinese New Year celebration.
