Spillikins is a game involving the removal of small rods from a pile, in turn, without disturbing the remaining ones; also the name for the rods used in this game. Its also known as pick-up sticks or jackstraws.

RE: human elbow
The human elbow is a complex joint located in the middle portion of the arm, connecting the upper arm and the forearm. It is a hinge joint that involves three bones - the humerus in the upper arm, and the radius and ulna in the forearm - and allows the arm to bend and straighten. Besides bending and straightening, the elbow joint also allows for rotational movements of the forearm. It is supported and stabilized by muscles, tendons, and ligaments.

RE: centralised
Centralised refers to a system, structure, or organisation where decision-making, control, or authority is concentrated in a single central location, individual, or body. This could apply to various domains such as government, business, computing, etc., where authority, power, or activities are not distributed or delegated among various individuals or subdivisions but handled by a central core. It offers uniformity, consistency, and clear control, but may lack flexibility and adaptability.

RE: rocket propulsion
Spacecraft propulsion is any method used to accelerate spacecraft and artificial satellites. In-space propulsion exclusively deals with propulsion systems used in the vacuum of space and should not be confused with space launch or atmospheric entry.
Several methods of pragmatic spacecraft propulsion have been developed each having its own drawbacks and advantages. Most satellites have simple reliable chemical thrusters (often monopropellant rockets) or resistojet rockets for orbital station-keeping and some use momentum wheels for attitude control. Soviet bloc satellites have used electric propulsion for decades, and newer Western geo-orbiting spacecraft are starting to use them for north–south station-keeping and orbit raising. Interplanetary vehicles mostly use chemical rockets as well, although a few have used ion thrusters and Hall-effect thrusters (two different types of electric propulsion) to great success.
Hypothetical in-space propulsion technologies describe the propulsion technologies that could meet future space science and exploration needs. These propulsion technologies are intended to provide effective exploration of the Solar System and will permit mission designers to plan missions to fly anytime, anywhere, and complete a host of science objectives at the destinations and with greater reliability and safety. With a wide range of possible missions and candidate propulsion technologies, the question of which technologies are best for future missions is a difficult one. A portfolio of propulsion technologies should be developed to provide optimum solutions for a diverse set of missions and destinations.
