It's a gorgeous ball, covered with Waterford Crystal triangles, shaped as a geodesic icosahedron.  Every New Year's Eve it descends in Times Square to mark the beginning of the new year.  Students can take a closer look at this construction and use our drawings to experiment with slicing an icosahedron in order to discover how this shape is formed.

You can use our short video below to demonstrate truncation.

For Adventurer members we have an editable Word docx and solutions with diagrams.
