Greg Gage is on a mission to make brain science accessible to all.

In this fun, kind of creepy demo, the neuroscientist and University of Michigan graduate uses a simple, inexpensive DIY kit to take away the free will of an audience member. It’s not a parlor trick; it actually works. You have to see it to believe it.

Greg helped launch a web site called Backyard Brains, which makes neuroscience accessible to school kids at an early age, so they can be fascinated, and eventually want to become a neuroscientist.

And leave it to YouTube commenters to think instantly of all the nasty things they could do with this app.
