The metal ball that is used in Olympic shot put events weighs 16.1 pounds for the men and 8.8 pounds for the women. Amazingly, Olympic competitors are able to toss that ball around 70 feet.

To do so requires the exertion of a lot of energy. Thanks to high speed cameras we can see exactly how much energy shot putters have to summon, because it is written right on their faces.

The hilarious and sometimes grotesque facial expressions shot putters make when they ply their craft have some similarities to the funny diving faces which have been well-documented this Olympics. But instead of gravity contributing to these facial contortions, shot putters look like they do solely because their veins are threatening to pop out of their necks and faces.
