BCB Wall Breaker
The next time you’re having a conversation around the water cooler, be aware that a British company has developed a way to make that water barrel into a projectile. The “Wall Breaker” is a non-explosive cannon developed by BCB International Ltd. in the U.K. It uses compressed air to fire plastic water drums that can knock a large access hole in walls, gates, doors – and apparently, vans – for military and security forces to gain quick entry.
The company says it uses a typical 20-liter water cooler drum, or about 5 U.S. gallons, and a U.S. gallon of water weighs 8.35 pounds. This suggests a projectile weighing nearly 42 pounds, heavier than most 105 mm projectiles, leaving the barrel at 984 feet per second, about a third the muzzle velocity of a 105 mm howitzer. Unlike a 105 mm howitzer, however, its target during typical use is going to be within a dozen feet, although range is quoted as “3 to 300 meters.” Of course, you can also put “sand, concrete, or other pourable materials” into the container, according to the company.
