Waterslides

And the Speedo is the most horrific part

Yes, the Sky Caliber will not be the first waterslide with a full loop—that distinction belongs to the old Action Park in New Jersey. But when it opens in 2016 at the revamped Action Park, the Sky Caliber will be the first full loop waterslide that shouldn't break your neck.

Riders will plunge down a 90-degree (that's vertical for you geometry-challenged folks), 45-foot long free-fall that sends them blasting through the 30-foot tall full loop at speeds up to 50mph. And you're going to be doing all of this inside what is essentially an alumni-reinforced coffin that they're calling an ultra raft vehicle. Where does the line between roller coaster and waterslide actually end?

Seriously, what's better than hanging out all day at Waco, Texas's BSR Cable Waterpark and riding the Super Waterslide The Royal Flush? Summer days don't get much better than this.

The Royal Flush at the BSR Cable Waterpark in Waco, Texas is a summer treat. The Super Waterslide has one of the best inclines into a launch into a pond that we've ever seen. But what you don't want to do is go down it backwards.

That's exactly what Matt Hess did, who thought he was being the brave and daring guy. There's a reason no one else was doing it backwards: because you'd smack your head on the incline. You can't get a great view of the head smack in this clip, but you do get to witness Hess's face which exudes pure pain.

Action Park is the stuff legends are made of. And they've added a nearly 2,000-foot long slip-and-slide to their plethora of ridiculous water park options. Just listen to the wind whipping as Action Park employee Jason Mulder flies down this epic ride!

Love waterslides and stepping disoriented into the bright Berlin morning after a night (or was it two?) of dancing your face off in some nameless concrete dungeon that you needed a password to get into? Well, we have just the thing for you: Black Hole, a wild waterslide in Bremerhaven outfitted with more than enough technicolor goodness to keep your inner party animal's most ravenous hunger satisfied. Check it out, bro.
