Steampunk time bomb

A time bomb (or a time bomb, time-bomb) is a bomb whose detonation is triggered by a timer. The use (or attempted use) of time bombs has been for various purposes including insurance fraud, terrorism, assassination, sabotage and warfare. They are a popular feature in fictional thriller and action films as they offer a way of imparting a dramatic sense of urgency.

Steampunk is a retrofuturistic subgenre of science fiction that incorporates technology and aesthetic designs inspired by 19th-century industrial steam-powered machinery. Although its literary origins are sometimes associated with the cyberpunk genre, steampunk works are often set in an alternative history of the Victorian era or the American Wild West, where steam power remains in mainstream use, or in a fantasy world that similarly employs steam power.
