Atlantis, Paradise Island, Nassau Bahamas: A 60-foot near-perpendicular chute-douche that sends you hurtling at 30 mph through a clear acrylic, habitrail-like tube submerged in a man-made shark-infested lagoon. Plus one GoPro. Plus several fruity pre-leap cocktails. Plus a complete lack of age-appropriate decorum. Plus a high probability of contracting water-park chlamydia.
