history clipart bookIn 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, and don't think too hard about what happens! Although it is overpriced for the short amount of time that the tour lasts, the two RV Gypsies found it to be fun.

sign: What is the Cosmos?

Cosmos Mystery Area is a unique and family friendly attraction, located amongst the beautiful Black Hills of South Dakota, 17 miles south of Rapid City on Highway 16, and only 10 minutes from Mt. Rushmore. The two RV Gypsies enjoyed a 30 minute tour of experiencing a world where mystery, science and comedy collided as they engaged in-hands-on experiments. They had an awesome time with the tour of mystery and fun. Leaving the highway, the two RV Gypsies had to drive on a dirt road.

For the first demonstration, the two RV Gypsies each stood on a wooden plank facing each other. The guide put down a level to prove that the ground was indeed level and not on an angle. As the two RV Gypsies looked into each others eyes and changed positions, their height from each other seemed to change. The photos do not really show much change however.

Karen Duquette was chosen to participate in a demonstration. The bench shown below is clearly leaning downhill toward the tour guide. Yet when Karen firmly rolled the tennis ball towards the tour guide, the tennis ball came rolling back up the slanted board back to her.

Karen Duquette stood on a small bench and although she was standing straight up, the gravitational pull of whatever magnetic force is located here, kept pulling her forward.

Karen Duquette did NOT find it easy to walk in the cabin.

Lee Duquette was picked to help demonstrate more of the mysterious gravitational pull in the cabin. Pushing on a heavy metal block was easy when pushing in one direction, but difficult to push in the other direction.

It was also difficult to walk outside of the cabin.

This board was supposedly level. Proof of that came form placing a tennis ball on the board and it did not roll downhill or move at all. But if pushed downhill, the tennis ball rolled back uphill by itself.

another demonstration the tennis ball did not move.

At first the lady appeared just a bit taller, or maybe even the same height as the man. But when they changed positions, the lady was definitely a lot shorter.

There was a lot more mysterious demonstrations, presumably mostly due to weird gravity pull. The tour guide made it a lot of fun.
