From Pathfinder Wiki

First, have a Pathfinder volunteer to generate some saliva, and collect it in a test tube. You will need about 1.5 inches of saliva in the test tube. To aid in salivation, the Pathfinder may find it advantageous to chew on some clean rubber bands. Do not use gum, as this will put sugar into the saliva and ruin the experiment. You will need a second test tube with an equal amount of water (1.5 inches).
