Dancing Sounds

Subjects: Physics
Topics: Soundwaves

Sound that you can see with your own eyes!

Want to have your students experience magical sound vibrations? This easy experiment focuses on pattern recognition between the volume of a sound and the strength of the vibrations that produced it. You will place a speaker in a plastic cup and stretch a colourful balloon over it. Then all you have to do is sprinkle some salt on top of the balloon and press play! The salt will dance to the rhythms like there is no tomorrow.
