Hello guys!! This is Dylan here! :D
And today, (well...a month ago) I have recently done a phonautograph project, which was sort-off successful, and it is completely made with KNEX. So I hope you enjoyed this post!! :D :) :wink:

Dylan,
thank you for the nice video that you made. I understand why it didn't work, but I am not going tot tell you. You have to find out it yourself.

Before you do these types of experiments, first THINK and do more simple experiments. That could be:
- speak (shout) into the plastic cup and feel gently with your fingers where it moves or trembles.
- Then place the pin, do the same experiment and try to feel in which direction the point trembles.
- Then try to make a set-up where the movements are recorded onto your sheet.
- I fear that in your set-up the movements are not visible in the line that you write.
- Try to understand why this is the case,
- and then try to think of an optimal set-up, where you can SEE the recorded movements,
- use a magnifying glass to look carefully to what you have made.

- After that you can think how to replay your recording.

Good luck.! Be clever, and think, think, think. That is also what Thomas Alva Edison did.
