Coffee Facts and Life Hacks [Video]

From Mentel Floss:

We kick off today’s episode of Scatterbrained with a timeline of how coffee gets grown and produced. Then, John Green tests coffee life hacks from the Internet, involving everything from coffee ice cubes to a recipe for creamer. We learn some history with the origins of coffee drink names and the old coffeehouses of England. Finally, a scientific study about caffeine shows us the best way to study seahorse pictures.
