The inner side of a spoon is concave, the outer side convex. If you look at your reflection in it, one side shows you upside down, the other side shows you the right way round and completely distorted. Since June 2012, you can find out exactly how this works at the Viseum Wetzlar. A giant spoon 2.3 meters long and 17 kilograms in weight has been specially cast in bronze for the Viseum and then polished and nickel-coated. Its surface may not tell who is the fairest in the land, but it helps us understand the meaning of the words concave and convex. It was designed, modeled and produced by the Württemberg Metal Factory (WMF) together with the Voxeljet company.
