Guess it should come as no surprise: Back in high school, when the incident occurred, I also greatly struggled to earn a “C-” in chemistry. It was then I decided to become a liberal arts major.

It was more about the story than the details!

Makes sense, as ethanol is produced by fermentation. Which is why beer has alcohol and carbonation.

Good catch. I’ve made that mistake myself. Did you know that CO2 — the fizz in our soda/pop/cokes — is a major co-product of ethanol production?

It’s true. Note “CO2 scrubber” in this chart. Here in Minnesota, many ethanol plants capture and sell their CO2.
