Apparently this monkey has never heard of efficiency.
As engineers we strive to maximize it.

Therefore i present to you a gravity bong (water lung) with WATER FILTRATION

TAKE IT ALL AND FEEL NO PAIN> MAXIMUM PRESSURE

Note: the bong pictured above is 1/2 the pressure it could be!
the point where it splits off the first chamber into two chambers halves your effective pressure through these parts

TLDR split chamber = 1/2 the pressure = weak smoke that doesn't hurt or carry as much thc.

maybe your time isn't too valuable then?
Efficiency :Achieving maximum productivity with minimum wasted EFFORT or expense
A gravity bong is the fastest you can get high, real high.
And no shitty waiting for my vape to come up to temp and babying the airflow through it.

I had this idea and dindn't bother to make a new thread about it so I'm just going to ask it here.
Would it be possible to modify an E-cig to vape weed?
Would it even be nessesary to modify it at all, since doens't e-cigs vape the nicotine fluid?
Also to add to the conversation about gravity bongs, I made one that consisted of two half liter bottles joined together from the mouth of said bottles. It had two hitholes/ places for easy-to-remove bowl, one of each on each bottle, and the point was that you could just turn it over and ight the bowl. I'll get you a pictue if I'm able to find it somewhere.

you didn't say you were optimizing for speed
>Achieving maximum productivity with minimum wasted EFFORT or expense
so having to cut up plastic bottles every few days because they can't be cleaned isn't wasted effort? all of your top shelf tasting as bad as swag because it burns too hot isn't wasted expense?
a vape can get you much higher than a gb, unless you think the 5 second headrush is the high, btw if you want a real head rush get some concentrates and don't waste them in your shitty piece of plastic

Look at that sexy glass bottle in the ms paint picture above... We don't all use crappy plastic and tinfoil.
And I 100% agree about the concentrates; isohash and whatnot, I kinda wish i was more willing to play with chemicals.
A vape is the least expensive cost wise for sure, and I certainly use mine when i'm running low. The prolonged dragging is a slow process though and the shitty diy one i made with a soldering iron wasn't worth the time to describe.

In respect to gravity bongs, it's more than a headrush, its actually reaching a higher pressure drop, and therefore a higher concentration of THC in the smoke. Fast and high concentration right to bloodstream.

In conclusion this is the best design I could come up with.

been there done that with the e cigs. Most efficient way is to use honey oil and mix with pg/vg base. That will work quite well with no modifications. I'd recommend something along the lines of an ego-t as opposed to an e cig.

didnt read the thread but I wish I could condense the vapor out of my vaporizer/ you forced air science nerds should get on that shit and report back

I created my own vapor bong out of some extra silicone tubing and a vodka bottle.

Just had to dremel a hole in the top and feed the tubing through.

The bonus is that it accepts the glass pieces on both the bag and the whip since I used the same size tubing.

I had this homebrew phase a few years ago during which I built a three chamber hookah out of a small Pom bottle inverted inside a large Pom bottle.
It was pretty rad, but I was living in a dorm at the time, so it could not last. I'm much better at working with plastic now, so maybe I'll try to recreate it some time.

Put either weed or salvia in one of your nostrils.
Use the other nostril as a carb.
That is all you need to do.

im way too lazy to ms paint a bong design, but ive always wanted to build a laser powered, induction assisted automatic bong with high accuracy pressure and pull speed tuning, but again, lazy

also already high
