Stellated Icosahedra

Straws and Geometry.


The Geometry class had the opportunity to do some craft work creating these striking wireframe polyhedra out of drinking straws and string. The shapes are stellated icosahedra: icosahedra have twenty sides each, and the stellated variety has a pyramidal spike jutting from each face, making the completed shape appear starlike. Drinking straws of various sizes were cut to size by the students and then tied together with string. The final products were light enough to be hung over the students' heads, on the ceiling of the classroom.
