A three inch diameter steel ball (if I could find one) would weigh just about 4 lb., and would fit nicely inside the PVC. So the interesting dynamic properties that Dave mentions could be realized without using tungsten. Just a cost-saving suggestion.

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.
