A Groan Tube is 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.[1]
The groan tube was invented in the early 1960s by Japanese toy manufacturer Kureo.[2][unreliable source?] The toy was first sold as 'Magic Noise Tube" (魔法音管). Mattel was the first company to sell the product in the United States in 1973.[citation needed] The Jibba Jabber toy, made by Ertl, produced a similar sound.
