For some of us, there are few things more exciting than a device that could get certain people to shut up. Japanese researchers created the 'new Speech Jammer gun'. Using a directional microphone, a directional speaker, and a distance sensor, the gun trips up its target by playing back their own voice to them at a slight delay of around 200 milliseconds. Researchers released a humorous video showing the SpeechJammer Gun in action, showing speakers apparently disoriented by the device.

Is Kate Middleton a gold digger? According to a new Chinese tourism video the Duchess of Cambridge only became a part of the royal family for the benefits.

In the bizarre advertisement - which was made by Chengdu city officials publicising a range of 'panda cabs' - lookalikes playing Kate, Prince William and the Queen are seen standing outside a palace trying to hail a taxi.

The 'Queen' is shown shouting 'taxi' - and whistling to get a driver's attention - before telling her 'grandson' and his wife they should save money by opting for a cab to get to the Jubilee celebrations.
