The Swimming Machine runs on combustion. Fill it with fuel – a blend of upright bass, sax, guitar, banjo, mandolin, violin, xylophone and trumpet. To ignite, whistle, shout, and sing. Oxygen is required. Stomp if it gives you any trouble. To get the pistons turning, stir in some tambourines, buckets, shakers, cymbals, spoons, a tin can and as many floor toms as you can get your hands on.
