Big O, Tokyo

4 of 16

When the first Ferris wheel was built in Chicago’s Lincoln Park in 1893, the center axel was the largest and heaviest part. About a hundred years later, engineers managed to build a wheel that doesn’t even need one. Within Tokyo Dome City theme park, the Big O was the first wheel without a center axel. To show it off, the park’s Thunder Dolphin roller coaster zooms through the wheel’s hollow center at speeds around 80 mph. tokyo-dome.co.jp
