Reducing friction with ball bearings

 Find two tin cans that have a deep groove approximately the top, such as paint cans. Lay marbles in single groove and invert the other can over the marbles to form a ball bearing. Place a book on top and note how simply the demonstration bearing turns. Oil the marbles and it will turn still more easily.
