What do a cup of coffee and cockroach pheromone have in common? How is Fix-A-Flat like sugarless gum? Is a Slim Jim meat stick really alive?

Along the way, he schools us on product histories, label decoding, and the highfalutin chemistry concepts behind everything from Midol to Hostess fruit pies.
