Roller coasters have delighted thrill seekers for centuries, and the history of this amusement park ride is full of interesting twists and turns.
The idea for modern roller coasters actually stretches back to fifteenth-century Russia, when people used to slide down the Russian Mountains on tracks made of ice.
The seats of the sled were also made of ice, although riders usually stuffed straw in the chiseled hollows to make the rides a bit more comfortable.
The world’s oldest operating roller coaster, Leap-the-Dips, in Altoona, Pa., was built in 1902. It’s 41 feet high and has an average speed of 10 mph.
