Physics: The sticks are curved, meaning that the center of gravity of every stick is below the point of contact with the other stick, giving it stability. It's like carrying your groceries in a bag. It cannot turn upside down on it's own. The difference here is that the point of contact is very small and low friction (slipping) had to be resolved.
