Bubble Hash

Bubble hash, named after the way it bubbles when smoked, refers to a specific type of hash made from ice water. To create the hash, the cannabis flower is placed in bags of ice water (called 'bubble bags') and stirred, which freezes it and then separates the resin crystals from the flower. These then pass through a series of sieves and ultimately form the bubble hash, while the plant material remains separated.
Bubble hash can vary in colour from light blonde to dark brown.
