👉 The sand weapon, also known as the sand cannon or sand gun, is a device that propels sand or other fine particles at high velocities using compressed air. It works by drawing in air through a valve, compressing it, and then releasing the pressure rapidly to force the sand out in a focused stream. This technology has been used historically for various purposes, including as a weapon in warfare and for practical applications like construction or clearing debris. The sand's high density and low weight make it effective for long-range projectiles, although its effectiveness can be limited by environmental factors such as wind and humidity.
