Running for your gate, carry-on in hand to make your flight on-time is the worst. Sliding to your flight's gate? That's the best.
This four floor-high slide located in Singapore's Changi Airport is designed to get you to your departure gate with the smallest number of steps possible. The only catch is that you have to spend S$10 at one of the airport's many restaurants or businesses. Seems like a reasonable price to me.
