2. Mistakes That Worked: 40 Familiar Inventions & How They Came to Be
Do you know how many things in your daily life were invented by accident?

SANDWICHES came about when an English earl was too busy gambling to eat his meal and needed to keep one hand free. POTATO CHIPS were first cooked by a chef who was furious when a customer complained that his fried potatoes weren’t thin enough. Coca-Cola, Silly Putty, and X rays have fascinating stories behind them too! Their unusual tales, and many more, along with hilarious cartoons and weird, amazing facts, make up this fun-filled book about everyday items that had surprisingly haphazard beginnings.
