Braided Stream

features air bubbling up through a fine powder constrained between 2 glass plates tilted at a 45° angle. The tilting creates a continually changing landscape evocative of aerial photographs of river drainage networks on Earth & on Mars. As air is pumped into the powder, it carves small streams. After the initial currents of rising air have carved channels in the powder, subsequent streams follow the paths of least resistance, further deepening & elaborating the drainage network.
