Soda Can Tensegrity

This Tensegrity structure is made from 2 beverage cans. At a glace you may wonder how the top can is being supported.

A couple of cans were filled with water to about 1 cm from the top. A couple of teaspoons of salt were added to the water and shaken.

The water in the cans was frozen by placing them in a freezor.
Once frozen, the side of the can was cut from about 2 cm from the top to 2 cm from the bottom using a craft knife. It was supported on a towel while this was done. The can was cut down again, making a strip of 3 cms wide.
The strip at the top and bottom of the can was cut around so the top of the can contected to the bottom by a 3 cm stirp, as shown in the photos. The ice was removed from the can.
This was repeated for the second can.

The corners where the can was cut were strengthened by adding some CA glue (super glue) and sprinkling on some baking soda. Wear plastic gloves while using CA glue to prevent sticking your fingers together.
The baking soda sets the CA glue straight away and give it some bulk and rigidity.

A monofaiment thread (invisible thread) was used to suspend the top can above the bottom can.

A small hole was drilled where the thread is attached to the cans. CA glue and baking soda was used to attach the thread to the cans once it had come out of the hole.

5 threads were used to attach the cans together, these have been highlighted in a photo above.
