Students from the Massachusetts Institute of Technology (MIT) have created a 3D printer that can produce ice cream in any shape! Kristine Bunker, Kyle Hounsell and David Kim were able to build the system using a blast of liquid nitrogen, which fixes the ice cream into place as it's released from the 3D printer's nozzle.
