Easiest to make is RSO, walmart will deliver 99% Iso Alcohol or if you can get everclear or shine it will work,
take two cups of either, put in mason jar and get cold in freezer,
set a 1/2 ounce of grinder ground bud in freezer, hour later mix with liquid,
shake up and down lightly for ten seconds, pour out thru three coffee filters into glass baking dish.
Put weed back in jar get two more cups liquid and put in freezer for hour, shake harder and twice as long, pour out into another container thru 3 coffee filters.
Place the two glass containers outside if possible, i cover with newspaper taped on four spots, allows air to pass but not too much foreign shit. by now you’ve got a slight buzz of fumes, if inside put somewhere they can evaporate without bother to you. when all liquid is gone you have a blow dryer or better yet a warming mat, heat dish slightly, scrape the ooze, get every drop…lol
place in something glass and put in freezer.
You can put a tiny line on a paper, knockout jointz.
You can Dab it, Smoke as a cap to a bong hit, etc.
You can put it in vape, but its thick, needs a warm vape.
Bubble Hash is my favorite, you can find alot about it where as the RSO is my version of Ricks original oil.
