Running the Leaf Surface Test
Dry the papers until fully blue, then fix one square to the upper and one to the lower surface of a leaf on a potted plant, held between glass slides or under clear tape. The square over the surface with more stomata turns pink first, because more water vapour escapes there. Pick the squares up with forceps, since moisture from fingers also turns them pink.
Keeping the Papers Dry
Store unused papers in a closed, dry container; a paper that has turned pink goes blue again after gentle warming. Wash hands after use.
