As the screws spin, they bite into soft ground and push material backward, creating thrust and keeping the vehicle afloat on mud, snow, or swamps. This unusual design spreads weight evenly and turns unstable terrain into a usable surface, proving that smart engine

WORLDWIDE ENGINEERING 🌍 on Instagram: "Sometimes imagination becomes monumental. In China engineers and builders constructed a giant snowman using real packed snow. The structure is massive, as tall as a house, and required cranes and careful planning to stack and shape each section safely. Watching it rise from the ground to its final towering form shows how creativity and engineering can turn even snow into a large scale spectacle. This project is a reminder that engineering is not only about
