How do salt crystals work?
If you are asking about the creation of salt crystals, then when in a sodium solution (Water and salt), the evaporation forces the salt to form together, rather then returning to the graniual form they originally started from. After evaporation, the seperation of salt and water leaves the salt residue in crystal forms. THis is all in refrence to water being the only substance to evaporate, so the best samples would be to leave the sodium solution out to slowly evaporate.
