Have you ever seen a tight-rope walker? If you have, you may have noticed that they often use long poles to help balance. When you look at the poles, you see that the ends bend down, often below the level of the tight-rope.
Maybe you can think of a way to make the forks act like the tight-rope walker's pole. Of course, if you do that, you will need something to be the body of the tight-rope walker and something like a leg for the tight-rope walker to stand on.
Have another think about the challenge and see if you can make the forks balance by making a model of a tight-rope walker.
