    "data": {
        "note": "The lightest wind that lifts a kite is where the aerodynamic lift just equals its weight: min wind = √(2 × mass × g ÷ (air density × area × lift coefficient)). A 200 g, 1.5 m² kite needs only about 1.6 m/s (6 km/h) — a gentle breeze. Lighter sails and bigger area drop the threshold, which is why featherweight kites fly when the flags are barely stirring and heavy ones sit on the ground.",
