Just in time for Hanukkah, second graders learned how to make hand-pressed kosher oil, with an olive press and centrifuge, under the tutelage of guest educator Rabbi Potash of Chabad. After selecting the olives and pressing out the juice, the students put the juice into glass tubes. After being centrifuged, the oil had risen to the top of the tubes. The rabbi told a midrash likening the floating oil to the spirit of the Maccabees, whose souls, he said, were always buoyant even in challenging moments during the three years of intense fighting. The students placed their oil in a hanukkiah, which they lit after the rabbi made wicks of cotton wool.
