Metals trivia of the day: tungsten darts

Maybe you've thrown darts before. It's an old sport, and technology doesn't have much to offer it, unlike, say, bicycling or Formula One racing. Traditionally, darts have been made of brass (an alloy of copper and zinc) and weigh 20 grams. However, more expensive darts are made mostly of tungsten. If darts can't weigh more than 20 grams in a tournament ... why make them out of a material that weighs more?The photo above shows a brass dart and a tungsten dart. The tungsten dart's barrel is smaller; its 20 grams weight takes up less space. Aha, you say: less aerodynamic drag. But no. If you're really accurate--better than I am--then you might be able to get two darts into a very small space ... like the bullseye.

And there's your metals trivia of the day.
