ABSTRACT:
A hollow, open ended tube of flexible, semirigid material which has internally projecting ridges that are so shaped and positioned as to produce a musical tone when air flow is induced through the tube by holding it at one end and swinging the other end around in a generally circular path to create a pressure differential between the two ends of the tube or by mounting the tube on the exterior of a vehicle in line with the relative airstream when the vehicle is in motion. The tube may be attached at one end to a hollow, extensible, spring-loaded handle.
