A short condensed explanation of Bubble Hash:
 
You have a number of bags, called bubble bags for some reason, and each has a screen in the bottom, the screen size (microns) progressively get smaller with each bag.
 
You put the bag with the largest/widest screen in a 5-gallon bucket, mix water, ice and your chopped up plant matter. Blend like you are baking a cake or something. Use a blender or an electric drill with a paint stirrer attached.
 
After fully beat to death you remove the bag letting all the water remain in the 5-gallon bucket. Squeeze the remaining plant matter to get rid of trapped water/resin-heads.
 
Have your remaining bags in another 5-gallon bucket with the finest micron screen bag on the bottom and the widest micron screen bag on the top. One at a time remove each bag. When you do you will fins some amount of matter on the screen. That is hash.
 
By the time you get to the finest micron screen bag that will be your very best most pure hash .. and those between the first and last will vary getting progressively better as the micron screen size gets smaller.
 
I never made butter so I will leave that to someone else.
