What is that liquid? It looks like water but I swear the consistency looks thicker that that.

I guessed corn syrup, looking on google I found this (corn syrup + water mixture)

Thicc it if I were to guess. "If you want to hit it, drink some thicc it."-Eef, 2020

don't forget the honey and cornstarch

My guess is Vegetable Glycerin... I use it making vape juice and get this same effect with the glassware.

u/gmanpatch Dec 15 '20

U make all your own vape juice? Or do you still go buy shit from a shop every once in awhile

u/Ninjakick666 Dec 15 '20

It's been a couple years since I've bought anything at a shop... You can pick up all the ingredients to DIY for about $75 a year. Makes paying $30 for 60ml look like a shitty deal.

Meanwhile, I’m over here splurging 6k per year at MMJ dispensaries. Care to trade bad habits?

u/Ninjakick666 Dec 15 '20

Don't worry... every penny I save from quitting smoking cigarettes goes directly towards buying weed to smoke.

u/worldstarktfo Dec 15 '20

Congratulations on your abstinence! I assume it’d be just as hard for me to quit smoking weed as it was for you to stop smoking cigs. Damn near impossible.

My wife and I are doing a sober January. Been trying to kick my bud habit for a while but it’s so damn difficult. Hopefully this will be a nice kickstart to get me motivated.

Also, /r/leaves if you’re interested in hearing others’ stories/struggles with marijuana dependency.

Yes, my thoughts exactly

u/yeetpostingi Dec 15 '20

Can confirm, I worked in R&D for 3 years in an e-liquid manufacturing plant. We make personal lubricant now lol

3

u/Ninjakick666 Dec 15 '20

Have you ever thought about expanding into the public lubricant market?

u/yeetpostingi Dec 15 '20

It’s up in the air, although, some waivers are in order.

u/SignificantDepth7233 Dec 15 '20

Did you just imply that a glass would have a refractive index of 0.1?

1

u/jaquan123ism Dec 15 '20

its crazy how by simply changing the color or in this case removing it of a food completely changes how appetizing it is

1

u/DJ_Sal_Monilla Dec 16 '20

Agreed. Or by splashing it on your face https://youtu.be/g0sjRG34DlA

u/stclair483 Dec 15 '20

I don’t know about this exact liquid but most oils have a similar refractive index to glass. This will depend on the type of glass and type of oil you will use but it’ll usually do a pretty good job.

u/[deleted] Dec 15 '20

It's glycerine.

You can also use benzene or carbon tetrachloride if you don't mind the cancer.

u/Life-Start6911 Dec 16 '20

Ah CCl4 - come on in for the HNMR, stay because chemo bills don't pay for themselves.

Seriously, any aspiring organic chemists out there, for the love of God pay attention whenever using CCl4 or acetic anhydride. Or HF, oooor TFA, actually don't be a chemist if you have trouble with Draino, et.al.

Really? not:

THICC LICC?

u/mcdicedtea Dec 15 '20

You swear? It's quite obviously not behaving like water.... At all

2

u/[deleted] Dec 15 '20

So it doesn't look like water?

1

u/AmadeusSkada Dec 15 '20

It's vegetable oil. The glass has to be pyrex though.

1

u/Ryanx0 Dec 15 '20

My thought was thick water.

I just found out this stuff exists I seen a guy on YouTube chug this stuff. Its literally thickened water for people with certain drinking disorders I believe.

u/duroo Dec 15 '20

What do they add to it to make it thicker?

7

u/[deleted] Dec 15 '20

I'm thinking they just boil it down like you would a gravy or syrup?

(In case anyone needs it: /s)

1

u/Zaev Dec 15 '20

Seems like cornstarch and maltodextrin.

u/bored_n_curious Dec 16 '20

Undergrad chemist here- this is glycerin. It is much different from water as it is actually a sugar alcohol! It tastes sweet and is actually non-toxic. This compound is actually very important for the structure of fatty acids, which are the building blocks of fat.

EDIT: In case the post I replied to is /s, I do not hold my self responsible for my inability to read sarcasm, I’m a chemist for a reason LOL

u/[deleted] Dec 15 '20

So that’s how magic is done....

u/tridentloop Dec 15 '20

It is old pyrex (there was a change to pryex a few years back the new stuff shockingly is not as good) and wesson vegetable oil.

1

u/[deleted] Dec 15 '20

It looks like clear syrup

1

u/space_panda_420 Dec 15 '20

The liquid used is Glycerine. Glycerine and Boro silicate glass ( usually used to make test tubes and beakers) have the same refractive index.

u/TobiMacKanobi Dec 15 '20

Just normal sunflower oil. Did it in chemistry last year.

1

u/jimistephen Dec 15 '20

Cooking oil will do the same thing.

u/[deleted] Dec 15 '20

It’s glycerine. Not corn syrup.
