Crystals form when a solution becomes supersaturated with salt, either by cooling or evaporation. Calcium chloride is an effective salt for absorbing moisture from the air. Research shows that salts can create crystals that capture evaporating water. Since science is an ongoing process, I think new questions should be investigated. First question is under what conditions do these crystals form effectively? For this question, the data we need is that crystals grow when the solution becomes supersaturated, meaning that there is too much salt dissolved in the water. The extra salt or other material takes the form of crystals to get supersaturated, a solution that can either cool down the solution or that some of the water evaporates. And the second question is what types of salt are most effective at wrapping water? The data we need for this question is calcium chloride absorbs moisture from the air effectively. It can attract several times its own weight in water, dissolving into a liquid brine if the air is humid enough and the temperature is high enough. And the research that is already being done on this topic is that salts can create crystals capable of trapping water when it's evaporating.
