Asteroid Collision we introduce the small object between the magnets as the pod gets close, representing an unexpected collision that pushes the pod away.
Docking Mechanism Failure, we weaken the string or tie a knot in it, suggesting a malfunction in the docking mechanism that pulls the pod back.
Internal Pod System Error occurred as we attach another magnet to the pod magnet with opposite poles, symbolizing an internal system malfunction that creates a repulsive force.
The materials are two magnets (representing space pod and docking station), a rope or string (representing tether or docking mechanism). Small object (representing asteroid or debris) and a paper towel roll (representing space station)
