Air bubbling up through sand between two sheets of glass creates the impression of a cross-section through a volcanic landscape. Pools of air and sand, like underground magma chambers, rise up through the denser substrate and erupt on the surface. Calderas form and collapse as viewers change the rate of air flowing through the sand. At high flow rates the entire mass of sand becomes a water-like fluid even though no water is present.
