The Three Specks' Trek

What is your body made of? Millions and billions and zillions of little specks called molecules. Every single one has a story of where it's been and what it's done before it became part of you! Three very different friends, an iron speck, a carbon speck, and a calcium speck, all wash off their rock in a storm, and then, after a few thousand years, have a surprise reunion in a bowl of spaghetti. Amazed to see each other again, they share the stories of where they've been with each other.
