Take cover! This hour of thrills will knock you off your feet. Lose your balance sand-boarding in Oregon, lean into a gravity-defying coaster in Taiwan, and get ready to duck and cover in a half-ton tank at Armourgeddon in England.

Prep your stomach for another 20 gut-wrenching thrills! We're riding the granddaddy of roller coasters in the United Arab Emirates, diving headfirst into a biplane in California, and sliding 163 feet straight down in Brazil.
