Students collect 8.5 million pennies to form 100-mile chain

Students in Southern California were laying out some 8.5 million pennies at a speedway track Wednesday, trying to set a world record with a 100-mile-long penny chain and help a school program at the same time. The money, about $84,500, will go to a program called THINK (Teaching, Helping, Inspiring & Nurturing Kids) Together.
