Ive been watching segments of the Curiosity Show (YT alg rabbit hole), and this project seems pretty fun. They use a cup, a balloon, and salt to visualize sound. They also use a mirror and a light source, much like we have seen with a laser elsewhere. Cool show.

Extra cool points for song selection @ 2:24
