This how the Army introduced the plastic explosive in the 1960s

Physics Uncovered on Instagram: "Explosive hydroforming uses the controlled energy of an explosive charge to shape metal into complex, high-strength parts — and the physics behind it is fascinating. A metal sheet or tube is sealed inside a water-filled chamber against a die. When the explosive detonates, a powerful shockwave travels through the water, forcing the metal into the die at extreme speed. Here’s the physics that makes it work: • Shockwave propagation: Water transmits the explosive pre
