The story behind this upside-down world

In 1952, two college boys searched the Black Hills, looking for the perfect spot to build a summer cabin. Upon their search, they stumbled into the mysterious world of the Cosmos. The old cabin areas

especially piqued their interest as the laws of logic and physics seemed to be turned upside-down. They continued to experiment and develop the demonstrations until they eventually opened their discovery to the public in 1953. Cosmos has been delighting guests with crazy fun ever since! Get your crazy on!
