The Discovery of Fireworks and Gunpowder

The second title in the Asian Hall of Fame series features returning characters Emma and Ethan, who observe a fireworks display for a Chinese festival. Their peppy animal friend, a red panda named Dao You, whisks them into the past to learn about alchemists and early gunpowder, followed by an overview of how fireworks began to be used in celebrations. Amara and Chin pack as much STEM information into Dao You’s history lesson as there is metallic powder in pyrotechnic stars: “In a mortar, the lift charge ignites to launch the shell up to 300 miles an hour, more than 1,000 feet high.” Calle’s bright cartoons infuse energy and enthusiasm into each spread. Ages 3–8. (Nov.)
