Make a thundering noise with this tube full of simulated storms, alien communications, or even a lion in the forest.
The possibilities are endless for creating scary or unusual sounds. Just use your wrist to make the spring dance and sound fills the air. Great for sound science demonstrations, or science experiments in class or at home.
One Thunder Tube
- 7" long
- 2" diameter
How does it work?Grasp the Thunder Tube in the middle with one hand and let the spring hang down. Make the spring dance by shaking your wrist and the air comes to life with sound! The tube works like a drum played by the spring “ sound waves are created in a column and resonate back and forth against the sides of the tube.

Kids were unable to tell what type of noise this was supposed to represent.

It made me want to chant! Great way to introduce students to the science of sound.
