World's Smallest Fidget Spinner Created with 'Nanoscribe' Machine

Researchers at Oak Ridge National Laboratory's Center for Nanophase Materials Sciences created a microscopic fidget spinner to illustrate the facility's unique resources. Their fidget spinner measures only 100 microns wide, or one tenth of a millimeter. The 'Nanoscribe' machine that built the fidget spinner is also used by researchers to create microfluidic and micromechanical devices for scientific applications. The instrument uses a focused laser to convert a liquid into a solid at a microscopic level. This process, similar to 3D printing, allows researchers to precisely design and build complex designs to make functional microscale devices with moving components.
