In this episode of “Ok, Now You Know,” Joe Garner takes listeners on an intriguing journey into the history and science of one of America’s most beloved snacks: popcorn. From its ancient origins to its modern-day presence in our movie theaters, popcorn has been a staple treat through the ages.

Popcorn’s story begins with archaeological evidence found in 1000-year-old Peruvian tombs and traces back to 3600 BCE in New Mexico, where the ancestral Puebloan people enjoyed this snack. Fast forward to the 1800s, popcorn solidified its place in American homes, especially next to cozy fires. Charles Cretors' invention of the first commercial popcorn machine in the 1890s revolutionized the snack industry, making popcorn more accessible and flavorful. During the Great Depression and World War II, popcorn’s affordability and sugar rationing led to its increased consumption. The science behind popcorn lies in a tiny drop of water inside each kernel, which turns to steam and causes the kernel to burst when heated. Today, innovations like microwave popcorn bags, introduced in 1981, make enjoying popcorn easier than ever.
