Answer:

You can use a block and an inclined plane (just a tilted board)

Place the block on the plane and gradually increase the angle the plane makes with the horizontal.

Static friction will keep the block in place (no sliding) until the angle between the plane and the horizontal is large enough. The block will now slide but is still under the influence of kinetic friction. Thus static friction is greater than sliding friction.
