A new trend in China is like being in a really fast spinning roller coaster....made of humans. The trend is called "human body helicopters," and it will most likely make you feel dizzy by just looking at them.

Human helicopters work by having at least four people standing in a straight line. The two people in the middle form the foundation by resting their arms on top of each other, and then the two outside people link arms with the people in the middle and kick their legs up. The result is a fast carousel-like human spinning roller coaster.

As you can see from the GIFs, the human helicopters don't usually last that long because it's difficult to maintain the speedy circular momentum. Check out the latest fad in China, but don't stare too long, otherwise you might start thinking you're the one on the helicopter.
