i was going to buy bubble bags and in the end i never did. but what i did try was gumby hash. there is a youtube vid. on how to make gumby hash by just using ice water and then siphon the water off in stages. i am sure the bubble bags will give you a much better quality of full melt bubble hash and someday i will get the bags. but i was happy with the way i did it and will try again someday. go to youtube and search for gumby hash. its an alternative if you dont have the bags.
