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?

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.
