This Super-Realistic Prosthetic Hand Can Give an Unexpected Twist to a Handshake

Living in an era of high technology, amputees and people born with missing limbs can get an advanced device that will make their lives much easier.

This Terminator-like robotic hand understands the muscle movements of its owner, Trey, who lost his right arm in a car accident. Besides looking and working just like a real hand, this high-tech prosthesis has one secret super power enabled by a simple downward motion: It can rotate a full 360 degrees!
