The cool moment is seen when 70 "mitzvah tanks" roll down the streets of New York to honor Rabbi Moshiach's 70 years of leadership on Tuesday (February 4).
A Mitzvah tank is a vehicle used by the Orthodox Jewish practitioners of Chabad-Lubavitch Hasidism as a portable "educational and outreach center" and "mini-synagogue" (or "mina-gogue") to reach out to non-observant and alienated Jews.
Mitzvah tanks have been commonplace on the streets of New York City since 1974.
