The London Eye, located in London, England, is the worlds largest observation wheel. The wheel was designed by architects David Marks, Julia Barfield, Malcolm Cook, Mark Sparrowhawk, Steven Chilton and Nic Bailey. It is made up of 32 sealed and air-conditioned passenger cars attached to the outer circle. It is not a Ferris wheel though. It takes about 30 minutes to ride around once, rotating at .85 feet per second. It is so slow that it does not need to stop to take on passengers.
The rim of the eye is supported by tie rods, and the wheel was constructed in sections that were floated up the Thames river on barges. After it was assembled, it was raised up by a crane at 2 degrees an hour until it reached 65 degrees. then it was left that way for a week so that engineers could prepare for the second part of the lift.
