STEM BOX: Levitation with Space Age Materials (Ages 12&Up with Adult Supervision) brain-teaser At the heart of everyMagnetic Levitation Few materials can be made to magnetically levitate stably above the magnetic field from a permanent magnet. Although you can obviously and easily achieve magnetic repulsion between any two magnets, the shape of the field causes the upper magnet to push off sideways, rather than remaining supported, rendering stable levitation impossible for magnetic objects (see Earnshaw's Theorem). Strongly diamagnetic materials, however, can
