In mid-october 2011, thorntons confectionery in derbyshire, england, set a world record for making a piece of chocolate weighing about 6 tons, 4 meters long and 4 meters wide. To celebrate the 100th anniversary of the factory, thorntons candy factory has specially designed this wonderful chocolate. This "big mac" chocolate was filled in a specially made large mold. It took 50 workers 10 hours to fill the mold with chocolate syrup and wait three days for the chocolate to cool completely.
