Summary
At a safe workbench, Lulu and Inky finally see what is inside the demonstration envelope: one cork slider and three corrugated paper ridges. They match every sound to a cause, test the explanation one last time, and learn why something happening after a question does not mean the question caused it.
A gentle mystery about causation, predictions, and changing one thing at a time. For families and children. No personal information or listener submissions are requested.
