Singapore's Changi Airport has been named the best airport in the world by Skytrax for the 12th time. Helping secure the title were its $1.3 billion Jewel, jumping nets, hedge maze, butterfly garden, and free movie theater. But why does this tiny island country of just 6 million people host 30 to 70 million travelers a year? And why does it spend billions on an airport? To find out, we spent 10 hours in the airport — and we didn't even have a flight to catch. Editor's note: At 1:44 in the video, we say the Rain Vortex waterfall runs 24-7. This is misstated. The waterfall is turned on from 11 a.m. to 10 p.m. Also, at 5:29, a Singaporean dish is referred to as chicken and rice. That is incorrect. It is called Chicken Rice. Insider regrets the errors.
