Scientists have developed a technology that allows you to create objects out of thin air (video)




A group of researchers from the University of Bristol have developed a technology that allows you to not only feel the objects created out of thin air, but to see them. It is based on – a generator of ultrasonic waves which are focused into a specific point in space, creating a 3D-tangible object. As for the visible image, the engineers are a little cheated and showed different shapes, giving the sound a container of oil. While the technology is perceived as something entertaining, however, developers are confident that they can find a use for it in practice.
