  • Interesting fact: In 1997 a Menorah was built in Latrun, near the main Jerusalem-Tel Aviv highway. It was more than 60-feet tall, weighed 17 metric tons, and took up an area of 600-square meters. A rabbi was lifted in a crane each night of the holiday to light the candles on the menorah, which was made of metal pipes.
    • Light metals those whose specific gravity is less than 5
