What? A cockroach dissection? Sound Waves? Electric signals?
This is great!
He actually dissects a cockroach on stage, hooks it up to a speaker and makes it move based on the electric signal produced by the sound. Lots of good possible daily questions. Since I am focused on sound right now I am basing it on that. Daily Question: What type of speaker produces a low frequency sound? Draw a picture of what that wave might look like.
