Japanese researchers have developed a handheld gun that can stop a person from speaking mid-sentence. The echoes confuse the brain and trip up the speaker. The researchers said the device is a conflict-resolution option that promotes peaceful discussions -- but it could also be used in libraries or in group discussions on people who interrupt others.
Chei! Japan has come again! Am sure lots of men would like this one especially if they have a nagging wife, or some women to shut their mother-in-law up or sef to shut some politicians who only talk without action! They should bring it to Naija jare, they will get costumers.
