I was eating at a Chinese restaurant when several spoons flew off of the spinning table in the center. The inward frictional forces of the spoons were less than the required mv^2/r that would have kept the spoons spinning in a circular motion. The spoons therefore traveled in a trajectory off of the table that is tangent to the rim of the table. The mustard, on the other hand, had a larger normal force and frictional constant that allowed the mustard to stay on the spinning table.

In this perfectly drawn picture, the block has a inward frictional force that keeps it on the table. One spoon flies off of the table at tangency since it does not have enough frictional force. A spoon that has a smaller radius is also traveling at a slower linear velocity than the other spoon.
