How Do Breathalyzers Work?

This week Reactions is checking out some breathalyzer science. What exactly is the chemistry behind how a little machine can tell how much alcohol you've had.

If you think you can beat a breathalyzer, think again; chemistry will land you in cuffs. In the American Chemical Society's (ACS') latest Reactions video, we examine how your breath can get you busted when you've had too much to drink.
