Bag of Ball bearings

This bag has an interior space considerably larger than its outside dimensions, roughly 2 feet in diameter at the mouth and 4 feet deep. When you peer into the bag all you see is  Ball bearings and you have 500 pounds worth of Ball Bearings in this bag.

If the bag is overloaded, pierced, or torn, it ruptures and is destroyed, and its contents are scattered all over the floor
