Glad Corn

Some of the world's coolest inventions were mistakes: wheat flakes (which led to bran flakes and corn flakes) were invented when John Kellogg accidentally left a batch of boiled wheat soaking too long, then decided to roll it out flat and bake it, and Silly Putty was supposed to be a new kind of rubber that just didn't work out quite right. So when one guy stopped paying attention to some corn (not popcorn, just regular corn) cooking on his stove and it (the corn, not the stove) exploded, it eventually became Glad Corn, a delicious and nutritious snack. $1.50 USD for a sample bag, or cheaper when you buy multipacks.
