ELECTRIFY YOUR SOUL! The thunder tube creates its song by gently shaking the drum so that the vibrations of the spring are transmitted to the head – creating a unique sound that exists somewhere between a gong and a dijeridoo. Covered in a lightning graphic, your hands will feel the electricity in the sound you generate. Can be used as a sonic centering device for friends. Allow it to reflect the energy of the lightning of your soul. Size 6" x 6"
