Ballistic gel is a synthetic material designed to simulate human tissue for testing the performance of firearms and ammunition. It is primarily made from gelatin and is used in forensic science and ballistics research to measure the penetration and expansion of bullets. This gel is often molded into blocks or other shapes to replicate the density and consistency of human flesh. By shooting projectiles into ballistic gel, researchers can analyze how different types of ammunition behave upon impact, helping to improve safety and effectiveness in law enforcement and military applications.
