What makes a bowling ball sink and a beach ball float? The answer is density! In this episode, we're unlocking one of chemistry's properties. We'll demystify what density truly is—a measure of how much 'stuff' is packed into a given space. You'll learn the simple formula (density = mass/volume) and discover how it explains why some objects are heavy for their size while others are surprisingly light. Tune in and find out what makes things sink, float, or hang in perfect balance!
