For many Jews the holiday of Chanukah is the lighting of candles - 1 candle per day for 8 days - in a Chanukah menorah or candelabra and the playing of the dreidel game. It is also some good eating... Actually, many of Jewish-related activities includes food... Anyway, we're talking here about latkes or fried potato pancakes, jelly donuts(sufganiot)and other goodies.
However...if you wanna know what Chanukah is really about, watch this YouTube video with Adam Sandler and chorus. Enjoy - I do! Fun!
