Sink or Float? The 60-second Buoyancy Test! #sinkorfloat #fypシ #density #science #stem

Quick, hands-on buoyancy demo: in 60 seconds we test what sinks and what floats! This fast-cut, kid-friendly science video shows simple sink-or-float experiments using everyday items (rock, cork, coin, plastic bottle, apple) to explain buoyancy and density in plain language. Perfect for classroom demos, STEM activities, DIY science at home, and parents wanting a quick lesson in physics. Learn how shape, material, and trapped air affect floating vs. sinking — all in one minute!
