Here's something you should never watch if you're afraid of heights: A group of Russian daredevils filmed themselves climbing (and hanging from) the world's second highest building, the still under-construction Shanghai Tower. It's absolutely terrifying.
The group, who call themselves Rasklovit, have filmed similarly terrifying videos before but never at heights like the Shanghai Tower's 1950 feet.
Your move, insane Ukrainian daredevils.
