B.A.N.G.

A person in a winter jacket stands on a wooden dock beside a frozen body of water, holding a device that emits a stream of smoke or gas into a hole in the ice. The substance spreads across the ice surface, creating a white, billowing cloud that expands and drifts across the frozen water, leaving a trail of white foam and ice fragments. The scene is set on a frozen lake or pond with a wooden dock, under overcast lighting conditions.
