Dixie cup spherical dodecahedrons

Fhrhy3K2Zvep2Ll77T.Medium
Here's a fun Instructable on how to make dixie cup spherical dodecahedrons - "The Dixiesphere is composed of twenty spherical-hexagonal 7-cup modular units, which you will construct first. Each hexagonal modular unit consists of seven cups hot-glued together such that one central cup is surrounded tangentially by six more cups. (The spaces between cups will look like equilateral triangles with concave edges, and the circular bases and rims of the cups will look like hexagonal close-packings of circles, but they will posess a slight overall curvature, as the circles define the surfaces of spheres.) It is important that the central cup contacts each of its surrounding six cups at their bases. It's a tight fit getting six cups around a center cup. Work quickly while the glue is hot to ensure that all upper rims and lower bases of the cups are flush, and that there are no superfluous gaps between the bases of the cups." - Link.

I made one of these using styrofoam cups and Elmer's Glue back in the '70s. I put a light bulb on a cord inside it and hung it in the corner of our living room as a lamp.

Wouldn't twenty faces make this form an icosahedron? Dodecahedrons have twelve pentagonal faces.

Wow. I guess all those hours playing Dungeons and Dragons weren't wasted after all.
