About Ingredients:
Join MIT-trained chemist and science educator George Zaidan as he tries to recreate everyday household products like toothpaste, lipstick, or shaving cream using only natural ingredients… and no recipe! He’ll have to decode long lists of intimidating chemical names, figure out what they all do, try and find natural substitutes, and then cook up the do-it-yourself versions in his chemistry lab (kitchen). While George may or may not succeed, we'll all learn something new and surprising about the products we take for granted every day.

I think the problem is the fact that the ink you used, which by the looks is fountain pen ink, is a dye. Like you said... the recipe calls for a pigment. Keep doing this show, I love it to bits.
You're absolutely right, it is fountain pen ink! Good catch. OK fascinating, thanks for the tip! And thanks for watching :)
minitos1 i adore his vids
i watch them all the time
just wish he would do say how much of the ingredients in which he makes
but pls make more vids ❤
I'm actually a chemical engineer currently working in Product Development at Expo. Octadecanoic acid and triester is used in some of our products as a means of ████ ██████ for the so-called "███████ ██████." The Octadecanoic acid and triester makes it easier for the █████ to ███████ in the ████████. This produces a ███████████, which is a ███████ and in ███████████ form. ███████████ and ████████ are extremely important parts of the process. They are needed for the ████████ of ███████. Without them, ███████ ██████ wouldn't be possible. The whole thing is pretty odd and boring-I know-but it's not like there is some big conspiracy or anything going on. Hope this helps!
Please don't tell me Expo redacted half of your comment? YIKES! Who's watching who? Or were you just being funny Mr David S???
I do not know what you mean. Everything is fine. Please return to what you were doing. Everything is fine. Everything is fine. Everything is fine. Everything is fine. Everything is fine.

;) gotchya! Clever! Hahaha Got scared for a minute. Thought the tin hat brigade might've been on to something 😱 ;)
Nice trolling
Are you still with Expo, sir? If so, we need you to develop a fountain pen compatible dry erase or heat erase ink for use with synthetic paper, like in Rocketbooks. Get right on it, sir!
Thumbs up for going through the MSDS sheets of 40 plus brands, bet that was a super duper fun time.
thanks!! so much fun....
HelloHarvardYo?
+George Zaidan A foam paint brush (purchasable at any home improvement or craft store) would have worked better as a felt marker tip, since paper towels are engineered to absorb liquids without releasing them back easily. I think felt is used because of how well it wicks moisture. But for painting the solution, a foam paintbrush would work just as well.
Another good tip, thanks Jack!
+George Zaidan The reason Dry Erase markers (and other office supplies) don't list what is in them, is that they don't fit one of two criteria: You don't eat them and you don't put them on your body (usually). Foods and items used on humans (and sometimes our pets) will have the ingredients listed mostly because of diet, allergy, medical, and religious needs to know.
Yup, right you are. That's why it was so hard to figure out what was actually in there.
I love this video and think this series is really amazing. Just wish you had follow up videos where you take these experiments even further.
I'm quite late to the party but I enjoyed this video. I would have liked to see an even deeper dive into perfecting your recipe, finding out some more details around the emulsifier, seeing how different brands compare in their chemical mix, perhaps a brief touch on any potential toxicity of the ingredients, etc
If it makes you feel better, generic dry erase markers also leave smudges all over the place.
Try to use water based pigment like that found in a water color paint set. The acetone should dissolve that very easily. Use more cetyl alcohol, also try this on glass since you can use more intense cleaners for that. Also it was very watery, try using less acetone and ethanol. Acetone is a very good solvent and you won't need much to dissolve the stuff together. Use a bit of ethanol since it takes longer to evaporate than acetone. You could try using a small paint brush for this experiment. If it is still very runny/dilute just air evaporate the acetone/ethanol or see if isopropyl alcohol is a better solvent than either solvent and use that instead. Try with or without an emulsifier to see if that makes a difference.
hey can you do glowing sticks? btw your videos are really great and kinda funny.
Yes! I always thought there were lightning bugs in there ;)
thanks!! and yes, added glow sticks to the list!
@nurdrage
When I first started this video I was wondering how you were going to do with with something non-edible but then you took out the MSDS and it all made sense.
love this series
We must know what's inside glow sticks!
yes
That would be awesome!
It's filled with love
I've heard the theory of it being alien urine... I'm doubtful though
no need for an episode. it's love spiked with alien pee. (jk. Added glow sticks to the list for future seasons!)
Really enjoy the series, and the deeper dive in this one.
thanks!!
Would love to see one on White Out or Hair Gel
Thanks for the information.
More of Curious Chloride please!
Also, what's in liquid foundation? (Cosmetics).
Salam Moselli omg I can almosf imagine him putting it on nonchalantly
it's gonna happen
Brilliant experiment. Well done.
As it turns out, you can use dry erase marker to remove permanent marker from a dry erase board.

George, you are so fun-ny. Y'all do a great job on this series.
Speaking of magic dry erasers...Every single time I use a (Mr. Clean...oops😉) "magic eraser" to clean my bathroom sink, or white kitchen cabinets, I am amazed! I wish I understood science as well as you others, but quite honestly it really is, Magic for me! One of the best and most useful products when it comes to cleaning. Just a thought for future episode. Thanks
Thanks!! I will add Mr Clean to the list :)
+George Zaidan TY,TY,TY
the chemical delivery system's material composition also plays a role in the overall function, i.e., "felt" may have superior qualities in this regard compared to paper towels.
Especially as paper towels are coated with wax to keep them from disolving in contact with water... Which is why you shouldn't use them to clean windows.
@@Othique Newspaper for cleaning windows ;)
So I found this because my daughter doodled all over my my brand new tablecloth with a dry erase marker and there is nothing online that worked to get out the stain. Solutions from Murphy's oil soap, isopropyl alcohol, laundry soap and dawn dish soap fail after fail after fail... But after watching this I tried acetone to remove the stain and voila! It disappeared before my eyes. What kind of magic? Can you explain why?
Thank you
I'm looking for a cool way to make a dry rail lube for my crossbow. I have Teflon and silicone powders
I guess if you mix ethyl alcohol propyl alcohol and fountain pen ink in equal parts and then add two pinches of detergent in it, it might work. The detergent will act as surftactant. It will also prohibit any permanent sticking of ink to the board. Maybe a little more proportion of ink is required to get darker color. I will try and let you know.
did you get any results from your experiments? I have done ink with soup and natural paint.
Have you tried this yet? Please share your results
ticklewit bruh come on did you do the experiment
That’s really neat and really cool that you can remove Permanent Marker with a Dry Erase Marker and you explained why it’s really neat and really cool too!!! ☺️😊🙂👍
Glow sticks would be cool. But I'd personally like to see some analog to commercial lotions!
Lotion is on the list!
I love these keep them going plzzzz
thanks!!!
I think your theory that they said the heck with the wax because I know I've have markers dry out and not seen any kind of wax layer built up so maybe some brands use it and others don't. Id like to know what ones do. It could also have been their way to beat a patient another company had no. Cause all you have to do to not infring on their patient is change some ingredients
Sir need more videos on this topic please
this is so great
Great video! Funny, informative, interesting and entertaining!
Thanks!!
Love this video.
Thank you for this. The study l made on dry erase marker ink gave me resin, ethanol, acetone and colour pigment. I can't figure out what the resume and type of resin it is. Please can you help out?
George, I really think you should create an r/stuffinsideyourstuff for recipe discussions and maybe help in future topics?
+George Zaidan my favourite educational series ever, is funny and you explain it awesomely! Keep it up :)
Thanks!!!
Are the xylene free dry earase markers toxic ? and do they cause health problems?
Yes they are highly, so use with care.
how do leds (the bright ones) work
You should have had a batch with no release agent as a control
this is great video..can i know how much of ethanol,acetone and cetyl alcohol required 100ml of ink?
Hello are you done it?
Can you please make a similar video on wet erase marker?
Totally do a follow up and put your ink in a marker to see if it comes out like a dry erase :)
what it the odor from please? and how bad is it for health? thank you very much,
aceton ? you mean the one used for manicure in nails? and dye using to color pants?
Love your videos!
thanks!!
If the nib of new marker became useless the how can we repair our. New marker please please please please reply
How much of each ingredient did you add like how are we supposed to know on how to make it
Wow!!!!
I had a bit of an idea, but right now I'm just like infobesity 😂
How about if u do like a subseries???
Like colored pigments?
Idk 😂
GREAT JOB!!!!
Hey George can you do hair spray please
tissue absorbed most of the ink.. it didn't come out that well . but it was well demonstrated
Could you make one about soap please?
Absolutely. It's on the list
Thanks! I admire your videos, they are amazing! Continue this series as long as you can please :-D
Wemal a thank you!!
Thumbs up George
0:27 Why Did You Block Expo?
We really want to do this perfectly.. do your best
Can you list the proportions of the ingredients you used to create your version in the video? Also isn’t ethanol highly flammable........
As long as you don't use open flames to warm flammable solvents (i.e. only use hotplates) and you don't warm it overly hot (particularly past it's flash point), there should be little to no risk of a fire
Depends on the solvent though
*HEY GEORGE! Can you do a video on gasoline?* How its made and the different octane levels and what all that means. PLEASE/THANKS!
yes! added to the list, thanks!
George Zaidan Awesome! Thank you!
So yeah. I'm a custodian in a 0public school. I've been looking for a way to get dry erase marker out of carpeting for years. If someone wants to invent that I'd be grateful
Hi
Did you try acetone?
MSDS has now been changed to SDS and companies have to go through and change all of their sheets. To me, it seems pointless, to drop the "M".
Whoa
I dig the ridiculously cheesy detective persona thing
why thank you. it was much more fun to do than i thought it would be
Why don't u tell us the measurements of grams and ml
yummm, McDonald's apple fritter dipped in coffee commercial. Totally worth it. LOL
I suggest you amp up your videos for more viewership with excitement by seeing if the things you make burn, at the end of every video.
I actually kind of like this idea... will run it by NG :)
hey love this show, by the way. keep it going for the nerd in all of us.
thanks so much!
Anyone knows the amount he uses?
So what's the difference between ink and dye then?
would ink (by itself) stay on the board?
I should have done this as a control -- but my guess is, yes.
Good job detective! :P
what releasing agent did he used, i m just confused
what's in bottled water?
Water.
@@tiffles4492 no way
why can you write over a permanent marker with a dry erase marker to remove it from a whiteboard?
Sarah Bostrom The release agent (and solvent perhaps) probably helps remove the pigment from both markers at once.
exactly! My guess is it's more the solvent than release agent, but haven't tried the experiment
well if there is alcohol in the DE ink then it makes sense that it would help clean off the PM ink since you can do that with normal iso alcohol. Its a solvent. The mechanical movement of the pigment on the board probably helps as well.
So....basically i need to mix my permanent ink and alcahol?
Oh and maybe insecticides too? really curious as to what's inside insecticides which kills insects.
good idea! will add to the list
MrPhebe9731 And more specifically why one kind of insecticides kill one kind of insects and no others? I mean, it's tricky but why they have not a kill-them-all acid or something like that. It apparently they have different ingredients each one of them.
You’re so fun
Please percent of chemical done
make a video about candy bars
How about Paints or maybe even printer inks :)
Paint is on the list! I'll add printer ink too
George Zaidan Nice ^_^
What is inside of glue?
it's on the list!
So can you explain why dry erase markers smell so bad?
do soda
Cola is on the list!
I must admit. Markers are pretty Ingenious...
Glasses cleaner and hair dye
Added to the list! thanks for watching
They say non-toxic but the smell is powerful. So its a lie, they are toxic.
Upload in hindi plse... If u can
I think I know the product name. Is it... Expo Marker?
im gonna be so clever
Yoy sure it didnt come off because of residual realease agent?
do a whats inside mouth wash
this guy knows how to make acid
I can neither confirm nor deny
I hate the spoiler at the beginning
