Disks or balls, consisting of concentric blue and white circles (usually, from inside to outside, dark blue, light blue, white, and dark blue) representing an evil eye are common apotropaic talismans in West Asia and the Balkans, found on the prows of  boats and elsewhere; in some forms of the folklore, the staring eyes are supposed to bend the malicious gaze back to the sorcerer. Known as nazar (Turkish: nazar boncuğu or nazarlık), this talisman is most frequently seen in Turkey, found in or on houses and vehicles or worn as beads. The word hamsa, also spelled khamsa and hamesh, means "five" referring to the fingers of the hand. In Jewish culture, the hamsa is called the Hand of Miriam; in the Levantine Christian culture is called the Hand of Mary, in some Muslim and Balkan cultures, the Hand of Fatima. Though condemned as superstition by doctrinaire Muslims, it is almost exclusively among the Near East and Mediterranean that the belief in envious looks containing destructive power or the talismanic power of a nazar to defend against them. To adherents of other faiths in the region, the nazar is an attractive decoration. A variety of motifs to ward off the evil eye are commonly woven into tribal kilim rugs. Such motifs include a cross (Turkish: Haç) to divide the evil eye into four, a hook (Turkish: Çengel) to destroy the evil eye, or a human eye (Turkish: Göz) to avert the evil gaze.
If the drop floats, the test concludes there is no evil eye involved. If the drop sinks, then it is asserted that the evil eye is cast indeed. Another form of the test is to place two drops of olive oil into a glass of water. If the drops remain separated, the test concludes there is no evil eye, but if they merge, there is. There is also a third form where in a plate full of water the "healer" places three or nine drops of oil. If the oil drops become larger and eventually dissolve in the water there is an evil eye. If the drops remain separated from water in a form of a small circle there isnt. The first drops are the most important and the number of drops that dissolve in water indicates the strength of the evil eye. Note that a secret chant is spoken when these tests are conducted. The words of the chant are closed practiced and can only be passed from man to woman, or woman to man.There is another form of the "test" where the "healer" prepares a few cloves by piercing each one with a pin. Then she lights a candle and grabs a pinned clove with a pair of scissors. She then uses it to do the sign of the cross over the afflicted whilst the afflicted is asked to think of a person who may have given him the evil eye. Then the healer holds the clove over the flame.
