In one stunning experiment, a leaf is placed on a glass plate and then electrified so that its corona discharge is captured on a photographic plate. Then the tip of the leaf is torn off and removed. When the leaf is again electrified and photographed, the resulting corona discharge is found to have the shape of the entire leaf, including the tip that has been removed. This experiment seems to show that the soul of the tip of the leaf is still present, and therefore shows up in the Kirlian photograph, even after the physical tip has been removed. However, this interpretation is false and easily disproven. The corona discharge at the location of the missing leaf tip is caused by leaf moisture residue left on the glass plate. If the glass plate is wiped clean and the ripped leaf is again imaged, the corona discharge no longer appears at the location of the missing tip. Similarly, if the ripped leaf is placed on a new glass plate, there is no corona discharge at the location of the missing leaf tip. This result shows that the famous torn leaf experiment is an example of a poorly run and incorrectly interpreted experiment, rather than an indication that leaves have souls which can be photographed.
