What's Inside a Golf Ball

If you've been paying attention, you know that insides of golf balls are unexpectedly beautiful—like psychedelic bullseyes or surreal alien planets. But what is all that colorful stuff made of ? As this video from Wired shows, golf ball is a serious piece of technology crammed into a mere 1.62 ounces.

The modern golf ball has come a long way since its leather and compressed goose feather days. The main stuff is cis-1,4-polybutadiene, or a synthetic rubber that quickly springs back into its original shape after being whacked by a club. Chemicals like zinc acrylate and benzoyl peroxide are also added to give the polybutadiene its desired flexibility. For your full chemistry lesson, watch Wired's explanation of what exactly goes inside a golf ball. [Wired]

I used to cut apart golf balls when I was a kid (and somehow still have my fingers). Back in the early 80's, it was tons of skinny rubber string - like a really long rubber band - surrounding a black rubber ball. It was pretty cool.
