David may have feet of clay

Experts believe that Michelangelo's famous statue of David is at risk of falling over due to cracks in the ankles caused by poor quality marble. Engineers fear the statue could crumble in event of an earthquake.

The statue is on display in Florence, Italy which is prone to earthquakes, leading some to call for moving David to a more stable area. Plans are underway to give the statue a CAT scan to evaluate its condition.
