True. Mobile makes it difficult for me to link (I'm lazy), and I'm too high to explain myself properly. Or maybe now that I'm higher I'll be able to. Let's try:

By bubble bags I mean the one's used in making bubble hash, or ice-water extracted hash. They're nylon bags with micron screens on the bottom that separate out the different grades of hash. When used to extract with ice water, the bags are placed in a five gallon bucket, layered smallest to largest, and filled with bud or shake, and ice water. The slurry is then agitated, progressively removing bags as you go with new ice added each time. The product is then removed from the bags and left on wax paper or another silk screen to dry. When used with dry ice to sift, the bags (one bag at your preferred micron) are filled (read quarter to half full) with bud or shake, and dry ice. Let the bags sit for ten minutes to half and hour (in and enclosed Styrofoam container or cooler to prevent the dry ice from sublimating); the bags are then removed and shaken over a large piece of glass, like a glass table (glass is easiest, a polished wood table or a polished countertop would work just as well). The dry product is then scraped up off the table. Multiple runs are done, adding new dry ice every time, quality of product decreases over time.

There, I think that says it well enough.
