Catch the Wave!
Catch the Wave! is an interactive booth with experiment stations to help you learn about electromagnets — what they are, how to control them, and how they are used to record and play back sound waves!

Stop by and play with permanent magnets, circuit-controlled electromagnets, speakers, microphones, and much more!
You can see demo videos of some of the roots of the experiments in this thread on Mastodon. The thread was also picked up on the Adafruit blog.
I wrote a quick post-first-event blog post, with hopefully more to come.
And you can read the original proposal.
