How to Make a Tetrastix!
Tetrastix are a non-intersecting arrangement of cylinders on the simple cubic lattice. Tetrastix arrangements can be made out of a variety of materials (post 5). Pencils will be used in this example, but any uniform rod or stick can be used. The pattern that is followed will direct the geometry and create a symmetric arrangement. Using only the compression from rubber bands and the friction of the rods, this arrangement can be used to make a beautiful and complex mathematical model.
Materials: 18 uniform sticks, 6 rubber bands, glue (optional).

To start, 6 sticks are brought together and bound on both ends with rubber bands to make a small bundle, step 1 figure17.

Congratulations! You now know how to make a simple tetrastix model! These basic principles can be extended and used to make even more complicated structures and an infinite array of novel designs.
