Sound Tubes are our absolute favorite sound toy. When spun in a circular motion, these tubes produce a tone. As the Sound Tubes are spun faster, the tone steps up in frequency. Due to the harmonics of the tube, there is not a gradual increase in frequency. Use these with our Wave Modeling Spring (Item SPR-1) for a fantastic standing wave demonstration. Colors and styles may vary.
