I live near a small lake. I used to tell swimmers that swimming towards the middle of the lake is harder because it's uphill. That's because if you drag a straight line from one side of the lake to another, it goes slightly below the surface because the Earth is round. In the middle of the lake its surface is farthest from that line so that's its highest point.
It surprised me how many believed that.
