Some Jews hold to the custom of performing Mayim Achronim (last water) before saying the prayers after food where they wash their fingertips. This is to purify themselves before doing something holy, as well as removing anything that might be on their fingers. This originates from biblical days when Sodomite Salt was a fear- the salt was so strong, if it came in contact with an eye it would blind the person. People began the custom of washing their hands after eating to prevent this from happening.

A mini pitcher of water and an empty bowl are passed around the table. Each person pours the minimal amount of water on their fingers, reaching up to the second knuckle. Water is poured once per hand and no specific blessing is said after besides for Grace After Meals.
