A drip rifle is a self-firing rifle which worked simply by having water from one soup can, drip into a lower soup can. When the water in the lower soup can, which was attached to the trigger of the rifle, reached a certain weight, the rifle was fired. This ruse could lead a battle front of defenders, into believing that there could still be troops opposing them, while the soldiers were being evacuated. Lots of drip rifles can be set to go off at different times, to give the impression that the enemy forces, were still in a defensive position.
“The Anzac soldiers in the Australian and New Zealand Army Corps of 1914 - 1918, would sometimes employ the specialized use of a drip rifle, in order to confuse or manipulate the opposing offense into believing that they were at a tactical disadvantage, when in fact, they were not.”
