* He mentions they even found a tube that had stuffing material rammed into either side, but at varying depths. The result was that the centre of mass of this tube was not the physical centre of the tube, so holding it at the centre of mass resulted in interference of two resonating frequencies, i.e. waves of modulated sound. | * He mentions they even found a tube that had stuffing material rammed into either side, but at varying depths.
