A military knife is thrown at a mannequin of a human head

A ballistic gel human head model reinforced with synthetic bone is struck by a thrown military knife, and the slow motion footage highlights the dramatic moment of impact. The blade pushes into the gel with smooth, controlled force, revealing subtle ripples, internal stress patterns, and the shifting of the embedded bone structure. The scene captures every delicate vibration and the expressive deformation of the gel as the knife settles inside, creating a detailed and visually rich demonstration of high-energy impact behavior.
