Self-Examination (No. 6 - PH values of my urine),


Ph strips, urine, ink.

This an (close-up) installation of a examination I did with PH strips that will change color when it makes contact with your urine (or spit) in order to tell you something about you PH value (ranges from 5.5 till 9, 5.5 is really acidic and 9 is really alkaline). I have done this since the 18th of November, 3 times a day(morning, afternoon, evening).
