Pop! The Invention of Bubble Gum

Walter Diemer, an accountant with the Fleer chewing gum company, slowly begins experimenting with ingredients, trying to create bubblegum. One batch is a near miss—his co-workers happily blow bubbles, but “the next day the mixture was as hard as a rock.” But with time, “top secret ingredients,” and the now classic pink coloring, he finally nails it: at a mom-and-pop store, kids blow bubbles for the first time. McCarthy’s thickly painted acrylic cartoons create an expressive 1920s backdrop with bug-eyed characters dressed in the era’s fashions. A closing section supplies numerous facts about gum. Unlike its subject matter, this history lesson is easily digestible. Ages 4–8. (May)
