The sound of a toy, which when turned on one end, makes a distinct 'groan' sound. This is due to a noise maker in the tube, that when it falls, vibrates in the air making the noise. The groan tube was invented in the early 1960s by Japanese toy manufacturer Kureo. The toy was first sold as 'Magic Noise Tube"
Hey bro do you know where the sound “Uuuua Auuuu” comes from?
Oh, yeah man thats just the sound my groan tube makes.
