David Helbich – Some Things Cannot Be Undone. Others Can.
– a wine glass, filled with any drinkable liquid (so, no bleach…) – a smartphone (or any other sound recording device)
Practice to play a tone with your finger on the glass. Learn how to start the tone quickly and play it without much interruption. Also try to play at the point where the tone almost breaks off or “starts stopping”, like a screeching door.
Once you are sure this more or less works, start to record yourself.
If you use your phone, either download a sound recording app, start a video (camera can be blocked) or send a voice message to someone. As long as you can play back the sound directly afterwards.
