Fascinating. There is definitely some magic in bells. If you ever have a chance go and take a look at Mingun bell on the outskirts of Mandalay in Myanmar (Burma).

At 90 tons, the Mingun Bell reigned as the largest ringing bell in the world until 2000. Now it's probably the second largest after the 116-ton Bell of Good Luck at the Foquan Temple, Pingdingshan, Henan, China.
