A game for pronation/supination and bilateral UE coordination
This video demonstrates the use of simple materials (glass jar, brass paper fasteners) and a circuit board to create a tilt switch. One child pronates and supinates with one hand while the other coordinates both hands to activate the switch. The materials could be changed to depending on the goals to heavier materials for endurance, change the shape of the cylinder for a pinch instead of a grasp, or to standing activity using bilateral grasp and coordination with a long cylinder tilt switch.
