An astonishing new sculpture by JK Brickworks (previously), a design team of Jason and Kristal Allemann, appears to defy gravity as it hovers in mid-air without assistance. Made of just a base, two rounded posts, and three small chains, the simple piece relies on tensegrity or tensional integrity. The design principle is based on the idea that a structure under compression within a system of constant tension will create a stable shape.
In this model, the LEGO pieces are compressed, while the chains are the prestressed tension members that provide the sculpture’s shape. When the top portion is lifted, the plastic links are in pure tension, which makes it resemble a floating object. If they caved in, the whole piece would topple.
