“Marshmallow” Snub Dodecahedron

Here’s a a student-built snub dodecahedron that resulted from a session I led in July 2018 at The College of New Jersey. It uses the classic “marshmallow and toothpick” construction technique, just with styrofoam balls in place of the marshmallows and 1/8″ diameter dowels in place of the toothpicks.

For geometric accuracy, the students did a ruler-and-compass construction on the surfaces of the styrofoam balls to find the locations at which to poke holes for the dowels.
