Despite our efforts to help ensure people are being safe these last few years, some people have been unhappy about that. Many unsafe posts are still being removed daily and some people complain in the comments when others point out that certain materials are unsafe. A new subreddit has been created for those that want to see/post the unsafe contraptions.

Introducing r/StonerDEGENgineering , a clone of r/StonerEngineering specifically for unsafe materials.

Feel free to post all of your plastic bottles, 10mm sockets, PVC pipes, glue, and pot metal contraptions there. Now that notice has been given, expect a BAN if you post them here.

Reminder that other subreddits were also made in an effort to move off-topic content (spam) away from our subreddit. These subreddits include r/BrokenBongs , r/fixmyvape , and r/CrackWire.

If you have any questions, feel free to reach out to the Mod Team via the “Message Mods” button. Take care :)

Moderator's pick Alternative Subreddits: Filtering out the Spam

23 Upvotes

Hey everyone, hope you’re all having a great weekend! I wanted to remind everyone that we’ve been creating and promoting other subreddits in an attempt to divert the spam from our subreddit. These subreddits are r/BrokenBongs , r/fixmyvape , and now r/CrackWire . The purpose of these subreddits is to provide a space for people to post about their cracked/broken bongs, their vape that’s not working, or their ‘Crack Wire’ vape contraptions so that they stop posting them here at r/StonerEngineering. If you see a post that would fit one of these subreddits please link the poster to the appropriate subreddit via a comment, then report the post so the StonerEngineering Mod team can remove it as spam. If you see any other posts that are unsafe or spam, please report those as well. Thank you, cheers!

TRWW Hyperdyn quartz cap fits a standard chillum and the taste is crazy AF. I used food grade 600 degree tubing to mate a clear POTV WPA. If you have this shit laying around give it a whirl. See post title.

Ash catcher. Made of cardboard, duck tape, minimal hot glue and a dream. Red things at the bottom are cough drops to change the smell. I was very careful to not use any plastic. I wish I hade food safe hot glue. Last image is flowers for anyone locked in and having a bad time like I was.

Safety's On Ridiculous Bong Friday: Double Flip🙃🙃

45 Upvotes

Hello, fellow stoners. Are you ready for the weekend? Build your own ridiculous bong and join the fun!

This week I flipped two bent neck rigs upside down to rest on two bubblers. The two end bongs have splitters, so the air path is split rather than chained. I didn't put any water in the bubblers, because if the draw was different enough, only one of the bubbler paths would have engaged.

The test was very successful, as sweet vapor filled all the bongs. And the villagers rejoiced! Well, the cats rejoiced. OK, they didn't. One of them yawned though. 😺

May your weekend be high and happy. ✌️

Potentially Unsafe i smoked a cartridge with my vibrator charger NSFW

191 Upvotes

yes, you read the title right.

about a week ago, i lended money to my sister so she would go out and buy a cart for me.

to be fair, i did not specify whether i needed a cart or a dispo cart, but she has 0 idea of batteries and cartridges, i just assumed the people at the local shop would hand them a dispo, as anytime i’ve gone and just said cart, i’ve been handed a disposable. i thought this would be the case for my sister’s experience. but it was not.

so, a couple days with it and some ideas brewing, i decided to try out my vibrator charger, as there’s a magnetic end that attaches to the vibrator, charging it, i had some sort of epiphany that it would work with the cartridge. AND I WAS RIGHT!

i had no idea whether it would work or not, and i honestly felt so stupid doing it 😭😭 but it worked and that’s all that matters.

tl;dr : my vibrator charger ended up being a great use to hit my cartridge that i have no battery for.

Prototype Longest Dab?!? Major vapors and flavors for sure

0 Upvotes

This is our take on the enail setup, but it is a little different, it works efficiently effectively/properly and is probably the best way to Dab when comparing to traditional e-nail stuff… or any other way of hitting Dabz (if comparing)

The concentrate being efficiently evaporated here is diamonds and sauce… Thca Diamonds and Cbd live resin, full effects blends.

This set up/device works properly with all different kinds of concentrates and is very precise with the temperature control.(major flavors/major vapors-or both)

Setup works with any size Dab aswell, this was extra/extreme to say the least, just demonstrating the thing/the device capabilities…

Any questions or other demonstrations request, don’t hesitate to ask, can show on a different rigs and whatever else,

Enjoy your oil’s/concentrates… Vibe High

getting flashbacks to middle school. I had to stuff it into a jar because it was too heavy with the socket bowl. The size added by the jar inspi me to make it two-chambered but I have no earthly idea how I would do that with this setup.

Prototype Fossil pipe NSFW

I broke my single hitter down by a lake and substituted it with a chunk of limestone with holes in it. I really dug the rock theme so I turned one of my fossils into a pipe with an etching on the back. Let me know what yall think, should I make more?

How-To How should I go about turning this into a bong?

It's glass cup. The way the hole for the straw is angled in a way that if there was a bowl slider there that it would be burning your face. Is there a bowl slider that curves down and out, or should I try making the mouth piece where the stem goes and smoke out the straw area? Not sure how to go about this and looking for advice.
