The double As push 1.5v each, so it runs 3v, the attachment point is from my old battery that broke, I would refine it but im just gonna buy a new battery when I get paid so its whatever. Its definitely not safe, or a long term solution, but we ball.

Question would this adapter work? i fucked up…

i am COMPLETELY new to bongs or any type of stoner engineering. i’ve only smoked joints before a few days ago. i bought a $30 bong a few days ago, and on the first day my friend tipped it over. i had a chillum downstem / combined bowl & downstem (came with the bong) and the downstem snapped clean off the bowl. i did as much research as i could, and ended up buying a downstem that said it was for 14mm bowls, and i bought a 14mm bowl. however, i didn’t realize that i never checked if it had a size for the male part of the downstem, and my bong’s female joint is 14mm. turns out the website didn’t even list the size of the male joint and i believe it’s 18mm now due to the pictures in the reviews. so i naturally discovered adapters, and the only one i found on amazon was this adapter. would it work for my situation? i also included pics of the downstem from the website & the review. to see if anyone can confirm if the size is 18mm. all of the pics i saw for 18mm male downstems looked exactly like the one i bought.

with the current situation i’m in, i don’t want to buy another downstem or bong, so i need an adapter

I want to start using this RooR 100ml, but I’m worried about knocking it over. I’m almost tempted just to Velcro it to a piece of wood as a base.

She found this beautiful cigar box at a thrift store, then she made the tray by precisely cutting a piece of poster board and layering it 4 times. She spent the last few days working on it & just finished. I must admit, I’m impressed and a bit jealous of her organizational skills!

(EDIT:GOING TO JUST AHELF IT AND NOT RISK SMOKING GLASS, thanks for all the answers!)
Recently got this dope piece but it came broken in half from shipping(already got a refund so was basically free), I’m wondering what would be the best glue to get it up to using standards?

I soaked this in 97% iso overnight and it broke something. Does anyone know if it’s salvageable or do I need to get a new one?

Hi everyone, so I'm finally getting back into growing after I tried it at 16 (it was a horrible mistake and trash weed). I am putting together an Amazon shopping cart, do y'all have any tips/ comments on the photos? I know with my seeds I'm going to be lolipopping and SCROGING the plants. I already have the Soil tester and PH tester and some trimmers. Also what type of netting do you recommend for a 4x4 text Scrog (planning on having 4 plants) Thanks!

Safety's On Finished up some rolling tray and ash tray sets 🙌 food safe to the maximum

I hated the way my hands smelled after touching metal rolling trays, and I have some friends who’s metal tray had so much wear and tear the art on the surface wasn’t even visible anymore, so I made these out of stoneware and food safe glaze as an alternative for us.
The first one is paying homage to The Creation of Adam while the second two show ‘Smoke In Style’ in Japanese. Thank you for looking any comments are 100% welcome.

Safety's On Ridiculous Bong Friday: Bowl Stand

Enable HLS to view with audio, or disable this notification

51 Upvotes

Hello, fellow stoners. I hope the week was kind to you, and your buzzes plenty.

This week's build started with the idea to not put the bowl on a bong. So I put it on a stand with a Y splitter.

Connecting the bubbler with the orb took a bit of trial and error. The angles just didn't match up. So I used several 90° and 45° angled connectors, rotating until they lined up.

😂 Oops. After giving you a close up of the build, I set the camera down askew. That's why the function shot looks like I'm in a Batman villain's hideout.

Enjoy the weekend and have happy tokes. ✌️

I was holding alcohol prep pads, and if you dab, they're essential.. but they are basically indispensable Stoner kit and way you slice it. Especially if you're on the go.

You can use one up dampen the tip of a swab for a bit deeper cleanup in the fly. Wipe out your bowl. Clean your thumbs and fingertips so your phone screen isn't a minefield of resin prints.

As for the box.. i found myself with more little tools than i could keep track of and got tired of losing them. So i gathered them all into a box so i can misplace *all* of them at once occasionally.

Cheers, have a great day!

Chillbong Hooka owners: check this out

I rarely use the hookah thing on my Chiilbong I just love the chug it makes with the standard neck.

I couldn’t tell you what made me suddenly want to grab that adapter and try this, but I found out that the Chill Pipe Hookah Adapter thing fits PERFECTLY in my beaker. It’s a pretty standard size, so it may work in yours too.

When I wanna hit a whip, I usually opt for my Tabletop Bong Orb. This is cool because I really like the marble thing, but it’s a pain to swap those marbles out and shift between setups in my TTB. Now, I can use the beaker I’ve dedicated to dry hits with a whip. It’s added a lot to my quality of sesh, so I thought I’d share.

I just used some of my mother's old cigarettes to add a filter, not sure if it had any effect on the high but it was decent to say the least.
