The Thunder Tube is a unique musical instrument that produces a thundering sound effect. It consists of a metal tube with a spring attached to it and a plastic membrane at one end. The tube is held vertically and shaken, causing the spring to vibrate against the membrane, creating a sound resembling thunder. The Thunder Tube is a versatile instrument that can be used in various musical contexts. Our Thunder tubes are handmade and come in a range of designs with vibrant dot paints on the surface of the tube.
