Mistakes That Worked
Product Number: 0631011
Every so often, mistakes result in fabulous inventions. Like the overcooked soap that floated and was named Ivory. Or the chef who responded to a customer’s complaint that his fried potatoes were too thick by creating the potato chip. Or the scientist who discovered her concoction protected her shoes from stains. Yep – it was Scotchgard. Rarely has science history been so engaging. With witty illustrations by New Yorker cartoonist John O’Brien. 96 pages.
