A man was caught on camera launching a firework rocket from his backside in a dangerous stunt.
Safety experts slammed the reckless behaviour after footage circulated on Twitter .
The video shows another man lighting a firework held in the other’s bottom.
As the fuse is burning, sparks appear to melt his top, with a friend shouting ‘it’s burned up your back, your t-shirt’s wrecked’.
When the main charge ignites, the man sprints forward and desperately throws his arms back to knock the pyrotechnic away.
