Tensegrity cube & tetrahedron by four rods The rods are placed as
diagonals of a cube. They are bent into arcs and therefore do not
connect with each other. The edges of the cube are formed by the red
thread connecting the eight ends of the rods to each neighbouring end.
The bent rods are positioned in such a way that the midpoints of the
arcs are equidistant from each other. The other red thread, which
connects the midpoints of the arcs, forms the edges of a tetrahedron.
The white thread ensures the rigidity of the square faces of the cube.
It could be possible to build a similar tensegrity structure using six
bent rods to create a tensegrity structure consisting of an
icosahedron and an octahedron.
