K'nex Tensegrity (floating) Platform

This Tensegrity (or floating) table or platform is made of K'nex and string. What makes it cool is that it looks like it defies gravity! Tensegrity was a design principle created by Buckminster Fuller (who is also known for the geodesic dome and Buckminster Fuller equal area map) to create light weight but very stable structures. Its stability comes from a careful balance of compression and tension at the joints. I hope you try and enjoy building this.

In addition to the K'nex parts shown, you will also need a roll of string and scissors to cut the string.

This unit has two extra side support blue rod pieces that will eventually be removed. They make adding the string to the structure much easier to accomplish as it temporarily makes the model rigid. After the stringing of the model is complete, the two pieces are removed.

There's nothing special here. Just construct the unit as shown.

Just a reminder, the two side blue rods that connect the top and bottom pieces will eventually be removed. They are temporarily providing a rigid structure for the assembly to make it easy for the string to be attached.

Add string to the model in the positions shown by the arrows. Be particularly careful to note which holes are being used in the two pieces in the center of the model. You may find it helpful to use a slip knot to tie the string and double-knot it after you get the tension right. After stringing the model together, you can remove the two blue rods supporting the top and bottom pieces.

That completes this project. I also wanted to share a modified version of this build that I designed. Thanks much for viewing this instructable. Please let me know if you build it and any additional ideas or suggestions you may have.
