Abstract: Workers briefly lifted Philadelphia's 2,000-pound Liberty Bell off its supports last month, giving the icon a taste of the stresses it will encounter this fall when it moves 300 yards to a new home. Last week, the National Science Foundation reported that two sensors clamped to the bell's famous crack registered displacements near the fracture of just several millionths of a meter.
