Seven. They are:
Cubic - all angles 90 degrees, all sides equal length
Trigonal - all angles 90 degrees, two sides equal and the third unequal
Orthorhombic - all angles 90 degrees, no sides equal
Hexagonal - two angles 90 degrees and one angle 120 degrees, two sides unequal and the third unequal
Trigonal - all angles equal but not 90, all sides equal
Monoclinic - two angles 90, one more than 90, and no sides equal
Triclinic - no angles equal, no sides equal

they are classified as crystalline.
Sports drink crystals are heterogeneous because you can see that it is made of many different parts.

Rocks with visible crystals are classified as crystalline rocks. These rocks are formed when minerals inside the rock crystallize and grow to a size that they are visible to the naked eye. Examples include granite and basalt.
Underground crystals are bigger where as crystals formed on the surface are smaller.
