　　Potato chips are very popular in the world. Do you know how they were invented (发明)? In 1853, a native (本土的) American named George Crum made the first potato chips. Crum was a chef (厨师) in an expensive restaurant in Saratoga Springs, New York. One day, a customer (顾客) did not like the French fries. He said they were cut too thick. That day Crum was in a bad mood, so he cut the potatoes really, really thin and he cooked them for a long time until they were very crispy (酥脆的). He wanted to make the customer dislike them. But the customer loved them very much and asked for more.

　　Other people wanted Crum's potato chips. Now, there was a new food on the menu-Saratoga chips. Soon Crum opened his own restaurant and made his special chips. It took a long time to make potato chips. People peeled the potatoes by hand. Then in 1920, the automatic (自动的) potato peeler changed everything. Now it was faster and easier to make potato chips. Now potato chips were not a specialty. They were a popular snack food, but only in the north.

　　A salesman named Herman Lay wanted to sell potato chips in the south. He sold potato chips in bags. His business grew. Today, Americans eat a lot of potato chips every day.
