A few more exciting shapes made from magnetic balls. Here's the original post. And here's the full coverage.
This is a dodecahedron - 12 faces and 20 vertices (the faces a dimpled, that's not part of a standard dodecahedron):
This is an icosahedron. Which is the dual polyhedra of the dodecahedron. Which means you swap the number of vertices and faces. So this one has 20 faces and 12 vertices:
This one is my favourite. It's a dotriacontahedron or a truncated icosahedron if you prefer:
But it's more commonly known as a buckyball. Bucky is short for Buckminsterfullerene. It's the name of the recently discovered molecular form of carbon first made in 1985. Before then we only knew about the crystalline forms: diamond and graphite.
In the molecular form, a carbon atom sits at each vertex of the bucky ball. 60 in total. It's also the pattern on a football:
So there you go!
The dodecahedron and icosahedron are two of the 5 Platonic solids. I'll do the other 3 in the next post. They are: the tetrahedron, the cube and and octahedron.
Any shapes you'd like me to make? Let me know in the comments.
