This bearing is cut from sheets of acrylic that have been glued together. A very strong magnet holds the bearing "upside down" against a sheet of acrylic (yellowish sheet) which has a steel plate on top (opaque black-looking smaller piece). When shop air is applied, the bearing moves very easily. At the end of the vid, the air is turned off and the bearing cannot be pushed around.
Design and fabrication by Kenny Cheung, video by Amy Sun. Cut on an Universal laser cutter at the MIT Center for Bits and Atoms. Designed in a manner to be reproducible at any fablab.
