What is a "bullet hit squib"?

A bullet hit squib is a special effects device used in film and television to simulate the appearance of a bullet hitting a surface or an actor. The squib consists of a small explosive charge and a blood or debris pack, which, when triggered, creates a burst of debris, smoke, or blood to mimic the impact of a bullet. This effect is often used in action scenes to provide a realistic and dramatic depiction of gunfire and its impact. Squibs are carefully controlled to ensure safety while achieving the desired visual effect.
