Why is this contraption different from all other contraptions?

As legend has it, thousands of years ago, a young Jewish woman named Jochebed placed her baby into a watertight basket set him adrift down the Nile. That baby was Moses, and though she couldn't possibly have realized it at the time, she had set in motion a chain of highly improbable events that would lead to the Jewish people being freed of their Egyptian chains, a forty year trek through the Middle Eastern desert, and the founding of the Israel. So, Jochebed could be considered the spiritual mother of the Rube Goldberg machine.
