Boy 1: Hey, did you know that potato chips were invented by mistake
Boy 2: Really What do you mean
Boy 1: Well, here on the bag it says that they were invented by a cook called George Crum.
Boy 2: When was that
Boy 1: Oh, it was back in 1853.
Boy 2: So, why was it an accident
Boy 1: Well, one day a customer came in the restaurant where George worked. He ordered a
plate of fried potatoes. When the potatoes came, he said they were cut too thick and sent
them back to the kitchen.
Boy 2: So what happened
Boy 1: Well, George was angry so he cut the potatoes really, really thin, and he cooked them
for a long time until they were crispy. And he put lots of salt on them so they were really
salty. He thought the customer would hate them.
Boy 2: And
Boy 1: And the customer loved them and asked for more. He told the other customers about
them, and soon everyone was ordering thinly-cut, crispy, salty potato chips.
Boy 2: And we're still eating them today. What a cool story!
Boy 1: Yeah.

The ever-popular hot weather treat known as the Popsicle was invented by Frank Epperson when he was just eleven years old. Born in 1894, Epperson was raised in San Francisco. One winter night in 1905, he mixed a soft drink made with soda water powder and water – a popular concoction at the time. He left a stirring stick in it and left it on the porch overnight by mistake.
Epperson found the fruit-flavored substance frozen to the stick when he awoke the next morning, as temperatures had dropped to record lows during the night. Though he is said to have tasted it and shown it to his friends, he did little else with his accidental “invention” for a number of years.

Epperson found the drink frozen to the stick when he awoke the next morning, as it was so cold during the night. Then he tasted it and it was quite delicious. So one of the world’s favorite snacks was invented.
