At the beginning a philosophy class at a university, professor stand with a few items seen dangerous at his desk.A jar mayonaisse empty, some rocks, some gravel, and sand.Students see such objects by curious.Them to wonder, what would professor that do and try to guess demonstration what will happen

Without saying a word anything , professor started laying stones small to in jars mayonaisse one by one .The students were dazed , but professor gave no explanation first. After stones came into the tube , professor speak for the first time that day .She asked to students do they think jars are full .The students agreed that jars are full .
