Mind control is just a fantasy—or is it? This TED Talk, entitled “How to Control Someone Else’s Arm With Your Brain," may prove otherwise.

Greg Gage is a neuroscientist and co-founder of an organization called “Backyard Brains,” which introduces the latest innovations in neuroscience to schools and the general public. The goal is to get kids interested in the complexities of the brain at a young age in the hopes that they'll get inspired, and someday pursue careers in neuroscience themselves. Securing the future of the field is crucial because, explains Gage, “20% of the entire world will have a neurological disorder, and there are zero cures for these diseases."

During his talk, he invites a couple of volunteers on stage to demonstrate one of the gadgets created by Backyard Brains, the Human-Human Interface kit. When one volunteer moves an arm, the kit moves the other volunteer's limb, too.
