David Kestenbaum is a great storyteller. He's a trained physicist who does science reporting because he seems to truly love putting a human face on stuffy scientists.
In this story about a new, experimental, non-lethal weapon he uses some great techniques that we can all apply to our radio reporting. He sets up the story with a "host intro" that really makes us want to listen.
Then, he starts his copy with a very simple technique...he goes back "to the beginning" where the technology was still young. He's found a way to illustrate just what the ray-gun does by using a personal experience of someone who helped build it, and who's been hit by it. We "feel" it in a way we wouldn't if the reporter just explained what he "heard" it felt like.
