Compounds Galore!

When I first began this blog, I had a notion that I would have a post for every one of my twenty-some polyhedron models. Of course, I now realize that I build them a lot more often than I do blog posts, so I am going to have to do them in groups. If I still had a set of the Platonic Solids (the most basic polyhedra), they would be a logical first post, but ironically I don't. I have made 3 sets of these already, but each time they seem to slowly get destroyed. A logical next post would be my set of Archimedean solids, but I still haven't completed them either. So this post is on my three compounds of Tetrahedra. I used to have a compound of two tetrahedra as well, but it
had an unfortunate encounter with the cat. Anyhow, here are my compounds of 5, 6, and 10 tetrahedra. The compound of five (in primary colors) is especially cool because it is chiral, meaning that it had both a left handed and a right handed for, like a pair of gloves (albeit one with 20 fingers). If you combine both forms together you get a compound of ten tetrahedra (shown at top). I don't mean to brag, but I like the colors that I used in that model. I used to have a compound of five tetrahedra that matched, but my sister Mary got into it and that was that. And the model sandwiched in between the compounds of five and ten tetrahedra (because I don't know how to rearrange the images on this post) is a model of six tetrahedra in pastel. I like pastels for polyhedra, though they can get boring after a while.

Well, it's dinner time!
