About a week ago I was just goofing around and noticed that the sound you got from an old seltzer bottle was a D on the piano:
Today my younger son was a little tired from a hike up Mount Monadnock, so I was looking for something a little lighter than usual. We decided to explore the sounds from the bottles a bit more carefully:
The short conversation in the first part of the project led to my son guessing a procedure for making a few more notes, so we tried it out. We didn’t get it quite right, but after the video below he returned to the sink and was able to produce the note he was looking for!
Fun little project, and I was glad to see that he was interested enough to want to get the note from the 2nd movie right after we finished 🙂
