Why be annoying when, with just a little bit of effort, you can be completely obnoxious?
To make this, it's important to leave the top completely intact. Drain your can by popping a hole in it with the slider, then remove the top and extract the disc.
There's a lot of variability in how loud this sounds. It depends on how long you've been using it, whether your other fingers are pressing or resting on the lid to dampen the noise, and whether there is an invisible crack in the seal on the opening.
The clicker works best if you press against the center-end of the tab with a fingernail (not your finger) and release rapidly. Also, keep your support fingers at the far end of the disc, otherwise it will act as a dampener and muffle the sound. It helps sometimes to rotate the tab a bit clockwise.
After a short while, repeated clicking will fatigue the metal at the scored edge of the popout-plate, causing a deterioration in function and sound quality.
