Blowing across a sheet of paper seems like it should push the paper away or force it downward. Instead, airflow can produce a result that feels completely backwards.
The explanation comes from the relationship between moving air and pressure. When air changes speed, the pressure around it can change too, creating forces that make lightweight objects behave in surprisingly unintuitive ways.
This simple effect connects an everyday experiment to one of the most familiar principles in fluid dynamics and helps explain why moving air can create lift.
Perfect for anyone curious about air pressure, Bernoulli’s principle, airflow, lift, or the physics hiding inside seemingly simple everyday experiments.
