Taryn Eason has Ehlers-Danlos Syndrome, a condition that gives people overly flexible joints and stretchy, fragile skin. It also allows for some really great party tricks, as Taryn demonstrates with her hands. Her fingers can do a ridiculous amount of stretching, which she reveals with a smile on her face for the entire video. She's probably happy to do it because it made her famously popular in elementary school. It's a remarkable use of her hands, right up there with the guy that can pull moles out of the ground and this deaf man's mesmerizing finger dancing.
