Spring

Real World Example

Imagine you're trying to squeeze the last bit of toothpaste out of a nearly empty tube. Just like how you apply pressure to the tube and the toothpaste finds the path of least resistance to emerge, groundwater under pressure finds openings in the Earth's surface to flow out as a spring. In both cases, whether it's toothpaste or water, the substance moves from a place of higher pressure to a location where it can be released, demonstrating how paths of least resistance guide flow to the surface.
