THE FUSE

Researchers at Northwestern announced that they may have cracked the drone-invisibility-code. Dubbed the Phantom Twist by its creators, the drone exploits faults in human vision to become nearly invisible to the naked eye. Rotating up to 25 times per second, it achieves the same optical illusion as propellers, spinning so fast that the human eye cannot follow it. Unlike its fanned counterparts, however, the drone lacks stand-still components that root it in your vision. Instead, the drone's propeller and body spin in opposite directions, According to its creators, the Phantom Twist is roughly 10 times less visible than your standard quadcopter and may be the closest we've come to realizing visually invisible aircraft.
