A microtome is a small machine that biologists use to slice specimens into very thin sections to examine under a microscope. Instructables user lemonie made his own out of Lego! In this video demo, the device cuts garlic in slices just 250 microns thick. That’s about twice as thick as a human hair. Seems like the Lego Microtome could be scaled up for slicing paper-thin prosciutto! Lego Microtome (Thanks, Christy Canida!)
