1)      When the connecting block is at the highest point of the wheel. The slice will pull up by it. Therefore, the slice will move to the nearest location to the triangle like the figure in the left.

2)      When the connecting block rotates to the left hand side of the wheel, the slice will be pushed down by the block. However, it does not have space to move down, it will slide on the pan and move away from the triangle.

3)      When the connecting block has rotates 180°, it moves to the lowest point of the wheel. And the connected slice will move forward to the longest distance from the triangle as drawn in the left hand side.

4)      When it turns to the right hand side of the wheel, the slice will move from a longer distance to a location nearer the triangle. After that, it will move back to its original position and repeat step (1) again.
