A replica mace is used to strike a replica human head

A medieval mace replica strikes a realistic ballistic gel head with embedded synthetic bones, captured in high-speed slow motion. Upon impact, one of the metal spikes pierces the skull, releasing vivid blue liquid that imitates blood. Each frame reveals the intricate details of the strike — from the initial contact and shockwave through the gel to the slow expansion of fractures and fluid dispersal. The footage provides a mesmerizing look at force transfer, material resistance, and the physical dynamics of a bludgeoning weapon in motion.
