If you’re reading this while in an office, you probably aren’t far from a soda machine. While coin-operated vendors are pretty much a staple of the workplace in 2015, it wasn’t always that way.

In 1951, Coca-Cola made a short film designed to encourage the presence of their machines in “plants, factories, mills, warehouses, drafting rooms, and offices.”

“You just seem to get along better with your work when you're fresh and refreshed throughout the day,” the (probably handsome) narrator asserts.

The 9-minute commercial walks the viewer through the placement, maintenance, and use of the cola machine, and, naturally, shows a lot of people enjoying it from those nifty glass bottles of yore.

The hard sell comes in the form of Coca-Cola as an investment in safety. It’s a tool for anyone whose job requires alertness, but especially those occupations in which a drowsy worker could spell out danger.  

A word of warning: You'll want a Coke if you watch this, especially when they start talking about the "ice cold zone" (which is apparently between 33 and 38 degrees Fahrenheit).
