I visited Mystery Spot in Santa Cruza, CA a couple of weeks ago. The operators of this site claim that it is a place where the laws of physics and gravity do not apply. They provide a number of demonstrations in support of these claims.
Mystery Spot is a visual illusion. Similar illusions can be found elsewhere, including the identically named Mystery Spot near St. Ignace in the Upper Peninsula of Michigan; Knott’s Berry Farm in Buena Park, California; the Oregon Vortex in Gold Hill, Oregon; and Idlewild Park in Ligonier, Pennsylvania, Spook Hill in Lake Wales, Florida.
There are many videos on youtube which have demonstrations from Mystery Spot.
After this visit, I was reassured of one thing: US is very good at packaging and branding .. be it Pepsi, be it iPhone or be it Mystery Spot(s).
