ATI made nursing school harder — my reaction after graduation

The holes that children dig at the beach can suddenly collapse, trapping a person up to the waist or even the chest in the sand. This happens because wet beach sand behaves like a granular material. When a hole is too deep or has steep walls, even a small vibration or pressure can cause the sides to cave in. Such collapses can trap a person, make it difficult to breathe, and in rare cases, even lead to suffocation.#beach #beachday #danger #fyp
