An expanding bullet is fired into ballistic gel through a drywall

A high speed camera captures the moment an expanding bullet passes through a sheet of drywall and enters a block of ballistic gel, revealing a striking interaction between the bullet’s energy and the fine drywall dust. In slow motion, the dust is seen flowing into the gel channel, swirling through its transparent structure and then being pushed back out as the gel ripples with vivid vibrations. This expressive sequence highlights the intricate behavior of particulate matter inside ballistic gel and showcases the detailed physics of impact through layered materials.
