World's smallest Christmas Tree
World’s smallest “Christmas Tree” is about the size of a DNA strand, consists of 51 individual atoms.

“A Physics student at Delft University of Technology creates world’s smallest Christmas tree made up of just 51 atoms from a perfect crystal lattice. The tree is exactly 4 nanometers tall, or 4 millionths of a millimeter.

The student Maura Willems for her graduation, uses high-powered microscope to build small structures, literally atom by atom, in order to study their quantum mechanical properties. Then changed each one’s position.”
