Supercooled water drops move spontaneously while freezing in vacuum. This self-propulsion phenomenon is caused by an enhanced evaporation rate from the frozen regions of the drops. The evaporating molecules carry momentum, and the drops acquire an opposite momentum, the same as in rocket propulsion.
