HYDROSTATICS AND PROPERTIES OF FLUIDS

Reelity on Instagram: "#onlyoriginals #theoriginals This Instagram reel shares a viral montage of physics experiments, from inverted glasses of milk and oil that don't spill to a bicycle with square wheels rolling smoothly, captioned simply as "amazing physics " to highlight their mind-bending nature. The non-spilling liquid trick demonstrates atmospheric pressure: when a card covers an inverted glass, external air pressure (about 10 tonnes per square metre) holds the liquid in place against gra

Rwefacts? on Instagram: "The post shares a viral video demonstrating a physics-based hack for removing shallow water from a pool or basin by submerging an inverted plastic cup to fill it, then lifting it mouth-down; atmospheric pressure creates a vacuum inside, preventing the water from spilling out until the cup is tilted. This trick exploits Boyle's law and atmospheric pressure (about 101 kPa at sea level), supporting a water column up to roughly 10 meters high, as confirmed by basic hydrostat
