As extraction techniques progressed, extractors realized that cold water and ice made the trichomes brittle and easily allowed them to separate from the plant material with a bit of agitation. Once the trichomes are separated, they are filtered and collected with various micron-sized bags. This extraction method produces a product called bubble hash. Although water is being used to make bubble hash, it’s not considered a solvent because the water does not dissolve the trichomes or the resin within. The trichomes are suspended in the water, separated much like oil and water.
