Now, device that zaps your brain to change mood

A new device has been recently developed that can zap people's mind to change their mood.

According to Tom's Guide, a private demo with Thync at CES 2015 involved people sitting with a small module attached to their foreheads for 15 minutes while electric currents passed through their nerves to their brain.

Since the product was still being finalized, Thync declined to neither take the photograph of the prototype module nor did they describe its shape, but offered only screenshots of its app.

The company mentioned that the effects of the session would last about a half hour after the session ended. The wearable device has two main modes of function: as energy drink substitute or to induce calmness.

The company has been working with the FDA to make sure its device was safe for general consumption, but was quick to assure me that the device was in no way harmful or invasive.
