Frank Epperson accidentally invented the popsicle in 1905 when he left a mixture of powdered soda and water on his porch overnight, creating the first frozen ice pop on a stick. He began selling the popsicles locally for 5 cents each. In 1920, Earle Dickson invented Band-Aids for his wife who often got hurt. He gave some to Boy Scout troops and sales increased greatly. In 1853, a chef named George Crum at a fancy restaurant sliced potatoes very thin after a customer sent back his thick French fries, creating the first potato chips which were a big hit.
