Years ago, I stumbled upon this story on the internet. In the original story, a college professor uses a mayonnaise jar, some golf balls, pebbles, sand, and coffee to make a point to his class about time management. I doubt the story is true, but the message is more relevant today than ever before and I liked the simplistic way it was presented...plus, I felt it might make a decent video. I hope my video rendition doesn't come across as preachy (that wasn't my intention), and that you find it relaxing and the sounds interesting.
