Torn Leaf Experiment
A typical demonstration used as evidence for the existence of these energy fields involved taking Kirlian photographs of a picked leaf at set intervals. The gradual withering of the leaf was thought to correspond with a decline in the strength of the aura. In some experiments, if a section of a leaf was torn away after the first photograph, a faint image of the missing section would sometimes remain when a second photograph was taken. If the imaging surface is cleaned of contaminants and residual moisture before the second image is taken, then no image of the missing section would appear.
The living aura theory is at least partially repudiated by demonstrating that leaf moisture content has a pronounced effect on the electric discharge coronas; more moisture creates larger, more dynamic corona discharges. As the leaf dehydrates, the coronas will naturally decrease in variability and intensity. As a result, the changing water content of the leaf can affect the so-called Kirlian aura. Kirlian's experiments did not provide evidence for an energy field other than the electric fields produced by chemical processes, and the streaming process of coronal discharges.
The coronal discharges identified as Kirlian auras are the result of stochastic electric ionization processes, and are greatly affected by many factors, including the voltage and frequency of the stimulus, the pressure with which a person or object touches the imaging surface, the local humidity around the object being imaged, how well grounded the person or object is, and other local factors affecting the conductivity of the person or object being imaged. Oils, sweat, bacteria, and other ionizing contaminants found on living tissues can also affect the resulting images.

Famous quotes containing the words torn, leaf and/or experiment:
“If we confine ourselves to one life role, no matter how pleasant it seems at first, we starve emotionally and psychologically. We need a change and balance in our daily lives. We need sometimes to dress up and sometimes to lie around in torn jeans. . . . Even a grimy factory can afford some relief from a grimy kitchen and vice versa.”
—Faye J. Crosby (20th century)
“frog pond ...
a leaf falls in
without a sound”
—Bernard Lionel Einbond (b. 1937)
“The man who invented Eskimo Pie made a million dollars, so one is told, but E.E. Cummings, whose verse has been appearing off and on for three years now, and whose experiments should not be more appalling to those interested in poetry than the experiment of surrounding ice-cream with a layer of chocolate was to those interested in soda fountains, has hardly made a dent in the doughy minds of our so-called poetry lovers.”
—John Dos Passos (1896–1970)
