This is a very creative project. Your explanation of standing waves, pressure nodes, and how levitation works was clear and scientifically accurate. I also appreciate how you documented the problems with both kits and used that as part of your investigation rather than giving up. That shows real engineering thinking. Your comparison of quiet vs. loud environments was thoughtful, and your reflections on why the device stopped working show good reasoning. Overall, you demonstrated impressive persistence and understanding of a complex topic.
Kudos!
