hey.. i liked your video on the sound waves.. i have to do a science project on sound waves.. is there any way you can tell me how to make that

Heyyyy , come watch sum videos plzzzz !!! Free beer for subscribers :) Plz rate ! thx

In your Sound Waves video, I find it interesting, yet obvious that the different acoustic frequencies produced different patterns.
My guess is that black paper was set atop a speaker...etc
just a few questions. How did you control the frequency, where was the speaker, and was it paper you used?
If this wasnt your experiment and dont know these, could you tell me whose it is?

How do you do that?
That is mind-blowing and so cool, too!
~Wow, Wow, Wow~

Love your soundwaves video!

~~what's up, your channel is tight~ sub4sub, i subbed.~~
