Americans do some bat-shit crazy things and call them adventure sports. Take this one for example. On the X Scream atop the Stratosphere Tower, a 69-foot pivoting track propels as many as eight passengers almost 30 feet over the edge of the building at 30 mph almost 900 feet above the ground. If you're trying to do the math, don't bother. Just trust me when I say it's really fast and really high. So if you've ever wondered if you have cahunas made of steel, try getting the first seat on this one.
12. Ice Swimming - Finland
From cahunas of steel, to cahunas of ice. Ice swimming in Finland is a thing, seriously. Not for those taking out their sweaters at 20 degree Celsius in India.
13. Devil's Eye Cave - Florida
It has been said that even today around 90% of the ocean on this planet is unknown. Even the bravest of the brave would think twice hearing that. This one is really intense. Four underwater passages extend from the pool under the opening, from 5 feet (1.5 m) to 90 feet (27 m) under the surface of the water. The passage called chamber 3, 70 feet (21 m) under water, contained animal and human remains and artifacts. The animal remains, which appeared to be associated with the human remains and artifacts, were from extinct (Pleistocene) species, including mastodons, ground sloths, camels, horses, dire wolves, bog lemmings, Florida spectacled bears, saber-toothed cats, and peccaries. The human remains have been dated to about 7,500 BC. Very, very intriguing.
14. Wing Walking - United Kingdom
This is just ridiculous. Do yourself a favour, don't bother about this.
15. Grand Canyon Skywalk - Mohave County, Arizona
One of the most recognizable and popular travel magazines, Travel + Leisure, has crowned the Grand Canyon Skywalk as the “best new bridge.” Located at Grand Canyon West’s Eagle Point, the Skywalk is the only place where visitors can step out onto a glass walkway nearly 4,000 feet above the floor of the Grand Canyon. Pretty cool.
