Catch the Wave!
September 16 & 17 at OMSI’s Oregon Science Festival
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.
I wrote a quick post-event blog post, with hopefully more to come.
And you can read the original proposal.
