To celebrate the 100 years of the revolutionary Niels Bohr Atom Model, we have, in cooperation with the Niels Bohr Institute of Copenhagen, created this beautiful mobile, which will surely decorate any home. In 1913 Niels Bohr developed his revolutionary model of the atom, from which new information technologies continue to arisefrom the transistor radio to quantum computers. Flensted Mobiles is now a family business for three generations. Flensted Mobiles are created so that the elements are in constant motion while the entire mobile maintains a harmonic balance. Each mobile is carefully assembled, and balanced by skilful hands. They are packed so that they are ready to hang. Size: 27 x 27 cm Material: Stainless steel, Wood
