He causes an explosion by throwing his cigarette !
Be careful where you throw your cigarette cigarette. The scene happened on March 29, 2017 in Tehran in Iran. A man wanted to get rid of his cigarette cigarette by throwing it into a hole in the ground. But no luck, the cigarette came into contact with emissions of methane from sewage and the ground has literally exploded under his feet. The man walked away, you can see crawling on the ground at the end of the video.
