Why the dust sticks onto ceiling fan blades ?
Answer:
As the fan blades cut through air, they develop charge due to friction. This leads to accumulation of dust particles as these dust particles as also usually charged.
The leading edges of the blades usually develops the thickest layer of dust. That's because the leading edge [the edge first cutting the air as the blade spins] encounters the most friction and develops the largest charge.
