Unlike dry rotted wood, the surface is made of the usual strong cellulose/lignin mix. As it is low-density but high in strength, balsa is a very popular material to use when making light, stiff structures in model bridge tests, model tree houses, and for the construction of model aircraft, as well as full-sized light wooden aeroplanes, most famously the World War II de Havilland Mosquito.
