As a Mongolian, the first thing to come to mind is, spraying milk right after someone special such as a family member leaves. For book sources. I believe it was described by Jack Weatherford in "Genghis Khan and the Making of the Modern World" or "The secret history of Mongol Queens". I find this interesting as "suu" means milk in Mongolian and water in Turkish, if I'm not mistaken.

I'm Jewish from Uzbekistan (Samarkand), and in my family growing up, we always threw a cup of water right as the car pulled away for a long drive.
