Have you ever seen towers like the Needle Tower in Washington, D.C? It looks like it's just a trick, but it is real. This method of construction is called tension integrity, or "Tensegrity". Tensegrity is achieved when many wires or cables are stretched between poles in a repeating pattern. This pattern normally resembles a geometric shape such as a hexagon,a square or a triangle.
In this instructable I will show how to make your very own desktop "Tensegrity Tower" using only some basic hardware store materials.
