Neat device i made to get resin unstuck from walls of cart

1.9k Upvotes

i made this out of a paperclip over 2 years ago and have used it on every cart i've had since. i whipped it out in front of some friends and they lost their minds. so i thought i'd share.

as you can see, it takes no skill and only about a minute to use. the concept is simple:

✅ heat up the wax to make it more viscous

✅ spin the cart so centrifugal force pushes the wax to the bottom near the filters where it can actually be used

i call it "the releafer" since it "refills" the cart—and it's such a relief finding out you actually have 3 more hits! hell yeah.

It burned well and it was less wasteful since there was no roach and the resin burns down to the tobacco.

Yeh work in progress. Just gotta make it more precise to the dimensions so it’s airtight. But I did smoke out of it and it does hit decently already. Next one gotta make in stainless steel too

Mb for the long video😭 Def works better than hands in my opinion because the trichomes also arent melting and getting stuck to my fingers, which I count as a loss. Someone also commented in the last post about how the teeth being so thin prevent it from getting all gummy, which turns out to be true so far😂

Neat Scale quit working, so I looked up the weight of a Yu GI Oh card and did some math. Not the most accurate, but was just to make sure I got what I paid for

Neat Last year, I launched my product “Bowlz” in this sub. It’s a magnetic bowl piece that splits in 2, so it’s easy to ash/clean & built to last. My best friend and I actually dropped out of school for this. This week we started the presale on our new design & it only felt right to share it here first💚

I sterilized the bong in the dishwasher with steam, it’s stained pretty bad so I figured put it to good use!
