A booby trap is a hidden device or setup designed to surprise or harm an unsuspecting person. These traps can be simple, like a tripwire that triggers a falling object, or more complex, involving mechanisms that activate when someone steps into a specific area. They are often used in military operations or by individuals to protect property. Booby traps can also be found in movies and video games, where they add excitement and challenge. While they can serve a purpose in certain contexts, they are often illegal and dangerous, posing risks to both intended targets and innocent bystanders.
