The 105-m drop tube at NASA/Marshall Space Flight Center has been used in a series of undercooling experiments on pure metals. Ti, Zr, Nb, Mo, Rh, Hf, Ta, and Pt were undercooled 17–20% of the melting temperature in a containerless, microgravity environment. Ir and Ru were undercooled to 13% Tm. Sample sizes ranged from 175 to 880 mg.

Ice-cold metal can freeze the skin when someone touches it with bare hands. Thin, anti-contact cotton gloves...
