Floating Orb: Spherical image, usually translucent white, though sometimes of
a reddish or bluish hue, which inexplicably registers on photographic film and videotape, also known as "Globule."
Globule: An anomaly where-in floating,
circular forms appear on photographs or videotape, which seem indicative of spirit activity. Globes are a natural containment formation of the miniscus of liquid, as in gas containing bubbles; perhaps the interaction of energy and a quasi-physical substance produced by spiritual manifestations results in a similar effect, the globules being an initial containment of energy. Presently, all we know is that they continue to appear, and extraneous possible causes such as moisture, light refraction or emulsion seepage, etc., have been considered and ruled out.
Ok...I know, shut up and go back to work!
