Let's experiment with saltwater to see how salt crystals are formed.
	Fumiko Yonezawa spent many years researching the properties of amorphous solids--that is, solids that are not crystalline in structure. However, almost all the solid materials familiar to us in our everyday lives are either crystalline in structure or mixtures that include crystalline solids. To get to know crystalline substances better, let's experiment with saltwater to see how salt crystals are formed.:
