Ill give you the quick write up. You get one of them scales you use to weigh drugs. You take it to dollar tree because normal packs balance for the weight difference now (there are guides online that will say which sets of packs are weigh-able tho and sometimes PTCG puts some out that are weigh-able by accident. ) You measure for every pack they have which is usually like 50 just stuffed in a box somewhere. You take the heaviest cards and you have like a 75% chance of getting a holo at the very least. The reason it works is cuz obv holos weigh more than just a normal ass card but in standard booster packs they put in that Pokemon Trading Card Game Online card in there which has two different weights. If theres a rare they put in a green one and if its a shit pack they put in the white one. This roughly balances the cards but like I said sometimes they mess up and packs can still be weighed.
I lost my scale so I haven't done this recently but it worked extremely well the few times I did do it. I was pulling full art holos left and right.
There are youtubers that buy 100 packs of new sets and try to weigh them any time a new set comes out so if you can't find a guide you can just watch a vid :)
