WATCH: Duo Performs Incredible Puppet Dance That's Bizarre But Breathtaking

Dancers know that successful duets rely on both performers to be equally active, in sync and have their emotions aligned. Whether it's a ballet pas de deux or stepping B-boys, dancers have to work together.

For dance teams creating the illusion of a puppet and puppet master, the demands are even greater: It takes a special skill to make an action look like a reaction between two people.

A video with an unknown origin circulating online shows two dancers in a beautiful, but bewildering, duet where it's not unreasonable to question if the female dancer actually is a puppet — assuming this video was not digitally altered.
