This hour-long special details the design, testing, and construction of the 168 foot 7 inch tall Verrückt, the world's tallest water slide at Schlitterbahn water park in Kansas City, Kansas.

The world's tallest trap door slide at Aqualandia in Spain, a home-made slide in Minnesota that cost over $20,000, extreme water rides at Aquaventure in Dubai, and a remote slide in the jungle of Mexico.

The 50 mile an hour loop in Switzerland that's the fastest on Earth; America's only ski ramp inspired slip and fly in Ohio; the $1.2 million dollar, 360-degree rush in Alabama and more.

Check out the first trap door slide in the world that tortures six at a time in New England. Brave Poland's record-breaking eight-foot wide, 610 ft long, 41-second tube slide.

Hold tight, there's a 70-degree drop that's terrorizing the south. Wet your senses in the world's first 5D water ride experience inside a theater. And a 6-story slide blasts riders down in a heart-stopping 15 seconds.

From a slide in Costa Rica atop a sleeping a volcano, to plunging 90-feet down a near vertical drop in Thailand, to the world's tallest and fastest waterside in Kansas - we're counting down the world's best rides.
