If we could look at the world around us with enormous magnification, we would see that it consists of many molecules that are constantly busy with something. We would also find out how a cup of coffee drunk in the morning affects our body (“hello, caffeine”), we would choose toothpaste more carefully (“is it with or without fluoride?”) and finally understand why chocolate fondant it turns out so delicious (“so that’s the secret!”). Chemistry is everywhere, it's part of everyone's daily life, so why not get to know this science a little better? The author of the book, part-time chemist and author of the unique YouTube channel The Secret Life of Scientists, invites you to look at ordinary and familiar things from a scientific point of view and even try yourself as an experimenter!
