Hey, I'm doing a project, I was wondering if it would work with a speaker instead of humming. I want to make it more sanitarry.

Hello,

Yes, the experiment would still work with a speaker instead of humming. Since this experiment is trying to demonstrate how sound waves can create patterns in small particles, instead of your sound waves coming from humming, it will be coming from the speaker to generate the sound vibrations!

I hope this helps!
