At the Royal Society’s Summer Science Exhibition in London, scientists make visitors gaze in amazement as small balls vanish before their eyes. This “invisibility stand” is one of the 22 projects being presented to the public this year. Among them are special glasses that help blind people “see”, tanks to capture sunlight and the so-called “smart traffic control”. Royal Society president Sir Paul Nurse told BBC News that the exhibition was a showcase not only for British science, but for the society in general.
