In Japan, tattoos are generally associated with criminals and organized crime, and as such, most Japanese water parks ban inked-up individuals from visiting.

"The same applies to people wearing tattoos."

There's an Abandoned Water Park in Disney

Disney World

In 1976, Walt Disney World opened the doors to River Country, but they were soon closed for good in 2001. The water park faced many challenges during its short lifespan, including bacteria-infested water and outdated attractions. Instead of demolishing the park and reusing the space, Disney chose to simply board it up; today, it remains on the grounds of Disney World, slowly succumbing to the weeds and wildlife. Some guests have dared to sneak in and take videos, but those who are caught face permanent banishment from the park. Disney is full of fun facts, so don't forget to check out these 20 Secrets Disney Employees Don't Want You to Know.

The First Indoor Park Was Probably Built In Your Lifetime

World Waterpark Canada

Nowadays, you'll find indoor water parks all over the world to enjoy year-round, but the first one wasn't actually built until 1985. World Waterpark in Edmonton, Alberta, Canada, is housed inside the West Edmonton Mall, and remains the largest indoor water park in North America to this day.

Public Pools Are Breeding Grounds For Bacteria

Unfortunately, kids (and even some adults) haven't quite grasped the concept that it's not okay to use the public pool like a toilet—and their excretions make for a not-so-pleasant swimming experience. One study from the Center for Disease Control (CDC) found that 58 percent of public pools contained E. coli bacteria, likely from fecal contamination. And Canadian scientists determined that one 220,000-galloon pool contained almost 20 gallons of urine. When you do go for a dip, rinse off beforehand to avoid being part of the problem—and this should go without saying, but don't pee in the pool.

The World's Tallest Water Slide Was Higher Than Most Buildings

On July 10, 2014, Schlitterbahn Kansas City opened the world's tallest and fastest water slide. The ride was appropriately named Verruckt—the German word for crazy or insane—as it stood at 168 feet. For the record, that's taller than the average New York building. From the get go, the record-setting ride faced its fair share of complications, and in 2016 the water slide faced its final blow when a 10-year-old rider suffered a fatal neck injury.

You Can Slide Through Shark-Infested Waters

Atlantis Serpent Slide, water park

At the Atlantis Paradise Island in the Bahamas, guests have the opportunity to tube down a five-story waterslide that ends in a "leisurely pass" through shark-infested waters. But there's no need to fret: The sharks are housed behind glass, so you will be completely protected as you gawk in awe. If you do visit the Bahamas, you should be more concerned about the tap water than a shark behind glass.

There Was Once a Slide So Risky That It Closed Immediately

Cannonball Loop Action Park Waterslide

New Jersey's Action Park was infamous in the late 20th century for being unsafe—the park once bragged about being responsible for "only six deaths," as if that were an accomplishment—but perhaps nothing at the park was more ill-conceived than the Cannonball Loop. The ride, as you might have guessed, was a gravity-defying waterslide with a loopty loop. Though there is much folklore surrounding the ride, it is said that the Loop was open for just one month during the summer of 1985 before the New jersey Carnival Amusement Ride safety Advisory Board shut it down.

One former employee told Weird NJ that the ride was "the brainchild of some Swiss guy [the park] imported on a weeklong visa." One young soul who was brave enough to ride the Loop as a child said, "Rather than sticking to the slide on the backend of the loop, I actually fell to the bottom. I smacked the back of my head on the slide and was nearly knocked unconscious."

Waterslide, water park

The idea for the waterslide was conceived in Minnesota, of all places. Faribault resident Herbert Sellner came up with the idea in 1923 when he built a large wooden slide that emptied out onto the water. Known as the Water-Toboggan Slide, Sellner's invention was a quick hit, and he later went on to invent other amusement park favorites like the Tilt-A-Whirl in 1926.

It might defeat the purpose of the ride entirely, but the original pirate ship ride was actually landlocked. Created in Tulsa, Oklahoma, in the 1890s, the ride was ironically called the Ocean Wave, and it sat at a circus where people could climb aboard and learn what being on the ocean was like.

Not All Water Parks Waste Water

Schlitterbahn water park

They get a bad reputation for being water wasters, but water parks are making a conscious effort to conserve water. Take Schlitterbahn Park in Texas: it filters and reuses 97 percent of the 3.5 million gallons required to run the park, and the other three percent are lost to evaporation.

Water Park Drains Are Disgusting

The First Ever Water Park Was Originally Built For Private Use

Lake Dolores Waterpark

In the 1950s, local businessman Bob Byers built Lake Dolores Waterpark in Southern California for his extended family to enjoy. Named after his wife, the park originally featured little more than a man-made lake and a campground; however, when Byers decided to open the park to the public in 1962, he added water slides, high dives, raft rides, and more. In 1990, Byers sold the park and it was run under the name Rock-a-Hoola and later Discovery Waterpark until its closing in 2004.

Orca whale

Orcas' skin is very sensitive to the sun. Usually, these creatures live so far below the ocean's surface that the UV rays don't affect them, but at SeaWorld, they spend most of their time in shallow water and thusly require black zinc oxide to protect their skin. Humans are also susceptible to sun damage, which is why you should use these 15 Hacks to Apply Your Sunscreen More Easily.
