Based on traditional percussion instruments, it is so simple to use.
At the end of the tube is a drumskin, with a long spring attached. When you shake the tube, the vibrations in the spring are amplified by the tube and the drumskin, and you get impressive sound effects.
Just gently shake it to create the sound of rolling thunder… shake it harder for a louder roll or pull the echo cable for a really big and surprisingly loud crack.
Thunder Tube Measures approx. 18.5cm x 6cm diameter.
