The Universe in a Cup of Coffee

Reactions is a show that uncovers the chemistry all around us. We answer the burning questions you’ve always wanted to ask, blending the worlds of science and every-day life.

The Universe in a Cup of Coffee

Season 4 Episode 1 | 4m 33s | CC

This week Reactions delves into the surprisingly complex chemistry behind coffee. The science runs deep in this one. The chemistry of the universe is, in a way, in your morning cup of coffee — from the evolution of caffeine as a defensive chemical weapon in plants to the swirling eddies of milk and coffee fueled by diffusion, Brownian motion and other phenomena.
