My maternal grandmother always made these 'eggs' for us as children.
"Oomancy is foretelling the future with eggs. The usual method is to drop the egg white in a plate with water and look for the future in the swirls. In England, the best time is New Year’s Eve".EL SALVADOR – CRACK AN EGG ON NEW YEARS EVE.
Some of the people from El Salvador crack an egg and put it in a glass at midnight. They leave the egg on the window sill and check it the next day to see if they will have a better future. If the egg is still okay, then it means that they will have good fortune. But if it’s rotten, then that’s something to worry about.
