I was very excited to observe salt crystals under foldscope .Salt crystals have wonderfully distinctive crystal forms. They might well be good subjects for introducing minerals, crystals and some of the more complex geometric solids.
The salt crystals are clearly cubic, even though some of the grains seem to be made up of overlapping cubes.
Salt is an ionic compound, sodium and chloride atoms (NaCl).
