An alternate method for creating hash involves extracting the resin glands in buckets of ice cold water. Marijuana is added to bubble bags, which are essentially silk screen bags. The mixture is agitated, and different types of bubble bags are used to refine the product. Since THC is not soluble in water, the ice water can be easily separated from the resin glands, allowing for a higher quality hash product than what the traditional method creates. Hash made with the bubble bag method is usually referred to as bubble hash or full melt.
