"You can't push on a string" I think this single string tensegrity structure is even more awe inspiring when he briefly holds it as a cantilever before standing it up right. If you skip to the second half of the video he shows how to use a block of wood to assemble the structure more quickly. https://www.youtube.com/watch?v=Ds-scY9qESE
Another builder made a taller and heavier single string tensegrity tower as well as a single string table. https://www.youtube.com/watch?v=8sUjpkmisBs Some history. The Latvian-Soviet artist/sculptor/engineer Karlis Johansons exhibited his first "self-tensile constructions" in 1921. The engineering and sculptural possibilities of such pre-tensioned systems were further explored by Buckminster Fuller and the sculptor Kenneth Snelson in the second half of the 20th century. (eg. see Snelson's "Needle Tower") The word tensegrity (tensile + integrity) coined by Fuller is now the common name for such structures. I have noticed that the first tensegrity structures focused on the use of straight struts, but now people are starting to explore the possibilities of using curved struts. Harry
