Little scientists ages 9 and up will love the new book from beloved science author (and dad of three) Sean Connolly. Despite the ominous title, all 50 experiments in “The Book of Potentially Catastrophic Science” are completely safe for kids and most simply use everyday household items. Each chapter begins with a scientific breakthrough that changed history and then provides experiments to demonstrate its findings. Kids can produce lightning in their mouths, make a water microscope or recreate an earthquake with Jell-O! $13.95 at amazon.com.
