Create a "gun" that makes you shut up

Mandar silence someone might be much easier thanks to an original and controversial Nippon invention. Two Japanese researchers have created SpeechJammer , a gadget that when "triggers" can cause a person to stop talking in seconds , interrupting his speech in midsentence.

Its operation is based on the psychologists discovered years ago that it is almost impossible to talk about when we hear our own words with a delay of only a fraction of a second. Kurihara and Tsukada have created a portable device with a built-in microphone, you record a snippet of conversation, and a speaker that plays 0.2 seconds later.

Both elements are directional, so it can be activated remotely, as if "disparásemos" a weapon, although in this case only beeps.
