17. Singapore Flyer:
These big giant wheels that go round and round giving you a spectacular view of the city are so cool, and the one in London is obviously pretty famous. But there is plenty of hard work and engineering skill behind the apparent simplicity. The Singapore Flyer is the world’s largest Ferris wheel and reaches 42 stories high, it comprises of a 150-metre high wheel built over a three-story terminal building, thus giving it a total height of 165 meters. It not only gives you a view of Singapore in totality but parts of Malaysia and Indonesia as well… Awesome!
