How does it work
Simply shake the thunder tube with one hand to make the attached spring wobble. The vibrations in the long, narrow spring are an example of standing wave (a wave that remains in a constant position) because the vibrations are moving in the opposite direction to the spring. When the sound waves reach the tube or diaphragm, they resonate up and down against the tube and result in an amplified thunder sound. Try creating different sounds by changing the strength of your shake or by running your fingers down the spring.
