Inside Fizzy Water: An Audio Experiment


What does it sound like inside a glass of water after an effervescent tablet is dropped in? Using a homemade waterproof contact microphone, Okrasonic.com finds out!


A few years ago, I decided to make a contact microphone based on instructions found online. (For example, a couple of good tutorials are here and here. For a deeper dive, check out this Instructables page.) Immersing it in a synthetic rubber coating made it waterproof.

Just last week I got around to making my first aquatic recordings with this little gizmo, plunging it into a glass of water and dropping in a “zesty orange” effervescent tablet.

Here’s a video depicting the maiden voyage of my submersible contact microphone:
