Have you ever wondered how the moon gets its many different shapes? Half moon. Full moon. A crescent. Science says it's due to illumination--and whether the moon lines up with other planets to prevent said light from reaching our eyes.

But in this nearly 7-minute short from Pixar, we follow the story of a young boy as he learns the trade of his father and grandfather...which ultimately makes our lives, and his soul, shine just a little bit brighter.

If you're looking for a little extra warmth today, spend the next 7 minutes watching this video. It's guaranteed to brighten your day just a bit.
