Interesting indeed. Such an object would stand nearly upright with the ball in the rounded PVC endcap. It might even walk a little ways, end-over-end, when pushed. Like a large "Mexican Jumping Bean," to recall a popular toy from decades ago.
However, FIRST is unlikely to build such objects in quantity. Ingots of tungsten are going for about $13/lb these days. Worked into balls, the cost per pound would go a bit higher.
Hmm. Highly unstable, heavy objects being manipulated by FRC robots? Autonomously?

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
