Accidental Discovery

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.

Come experience for yourself what continues to amaze and baffle visitors for 67 years.
