On the Origin and Evolution of Icicle Ripples

Loading video...

Caption: These are movies of three icicles grown under identical conditions of ambient temperature, water supply rate, and nozzle temperature. (1) was made with distilled water only; (2) was made with distilled water plus NaCl with a mass fraction of (8.0 +/- 0.2 X 10^{-5}; (3) was made with distilled water plus NaCl with a mass fraction of (1.278 +/- 0.002) X 10^{-3}. The icicle grows from a rotating support over a period of about 10 hours. The support looks like its rotating fast, but actually takes about four minutes per rotation.
