Wave the green flag and watch. There is one picture that has body leftovers form the eruption, so if you get freaked out easily then I suggest not watching.
Credit to Bastille for the song and Google Images for the pictures. If you don't know what happened then this is it below: In 79 AD the famous volcano Mount Vesuvius erupted and wiped-out a lot of Pompeii (where Mount Vesuvius is located). Many people where killed.
