The process involves creating a device, often from readily available materials, that utilizes gravity and water displacement to deliver a concentrated inhalation. The resulting apparatus typically consists of two containers, one fitting inside the other, where the inner container is submerged in water and then slowly lifted as it fills with smoke drawn from a lit substance.
The creation of such a device is driven by a desire for efficient consumption. The resulting hit is often perceived as more potent due to the rapid intake of a concentrated volume of smoke. While the origin of the device is difficult to pinpoint, its widespread adoption is likely attributed to its simplicity and the ease with which it can be constructed from common household items.
