A booby trap is a device or setup designed to surprise or harm an unsuspecting person. These traps are often hidden and can be triggered by movement or pressure. They are commonly used in military operations, hunting, and even in pranks. The goal is to catch someone off guard, making them a popular element in movies and video games. Booby traps can vary in complexity, from simple mechanisms like a falling object to more elaborate systems involving explosives. They have historical significance, especially in warfare, where they can protect territory or deter intruders. Understanding their mechanics is important for safety and prevention.
