Weeping Virgin Mary

There's news today (May 27, 2015) of a weeping Virgin Mary statue in Liloan, Catarman, Camiguin.  There were investigations in the past by the church about these weeping statues, many were made by making a hollow statue, placing red liquid material or wax inside and placing a tiny hole in the eye such that when rubbed or when temperature is high as during summer or when a church is packed, it the packing material or wax in the tiny hole melts (or just rubbed) and red liquid pours from the eye like a weeping Mary.  Of course there are true genuine miracles but many resort to these crimes just to raise money in their chapels and increase the flock.

"How to make a weeping statue:
What is needed is a hollow statue made of a porous material such as plaster or ceramic.  The icon must be glazed or painted with some sort of impermeable coating.  If the statue is then filled up with a liquid (surreptitiously, through a tiny hole in the head, for example), the porous material will absorb it, but the glazing will stop it from flowing out.  If the glazing, however, is imperceptibly scratched away on or around the eyes, tear-like drops will leak out, as if materialising from thin air.  If the cavity behind the eyes is small enough, once all the liquid has dripped out there are virtually no traces left in the icon.  When I put it to the test, this trick proved to be very satisfactory, baffling all onlookers.
Dr. Luigi Garlaschelli from Pavia University published in Chemistry in Britain."
