tin cry is often demonstrated using a simple science experiment. a bar of tin will "cry" repeatedly when bent until it breaks. the experiment can then be recycled by melting and recrystallizing the metal. the low melting point of tin (only 232 °c, or about 500 k) makes re-casting easy. tin anneals at reasonably-low temperature as well, normalizing tin's microstructure of crystallites/grains.
