Kingda Ka
Kingda Ka holds the title for the world's fastest and tallest roller coaster. It reaches speeds of 128 miles per hour (206 kilometers per hour). It is 456 feet (139 meters) tall with a 418-foot (127.4-meter) drop. And if that is not enough, the train rolls 90 degrees on the way up and 270 degrees on the way down!
