This is a good example of how easy it is to fool people if they don’t have their own understanding of how things work.

Highlighting this has been a priority in my parenting. My child is having a great time trying to scare friends about the dangers of the chemical dihydrogen monoxide, which is found in a surprisingly large number of manufactured foods.

Cooking is chemistry anyway.

But that's total nonsense. Everything in our physical world (including water, air, food, and human bodies) is made of chemicals. They can be naturally occurring or artificially manufactured.
