40 Incredible Inventions That Were Born Out of Chance

Some days, I get thirsty in a way that mere water cannot quench. I need something icy cold and insanely sugary—a slushy. Fortunately, I can get a slushy at basically every gas station in town. But that wasn’t always the case; it wasn’t until the 1950s that the owner of a Dairy Queen in Kansas invented these delicious drinks.

His soda machine had problems, so he stored the soda in the freezer until it was fixed. When he pulled the frozen soda out, he found that it had a fun, slushy texture that turned out to be a big hit when he started selling it to customers. Soon, slushies were being sold all over the world.
