- In this video, we are going to be making some calcium acetate from eggshells. In the future i will make some from Tums, but the process is going to be a little different and there will be a bit more chemistry involved.
The calcium acetate that we make here is going to be used to make flammable jelly and acetone

i guess im asking randomly but does anyone know of a tool to get back into an instagram account?
I was stupid lost my account password. I would love any help you can give me
@Beau Kyle instablaster :)
@Rowen Kendall thanks for your reply. I got to the site through google and Im waiting for the hacking stuff atm.
Takes quite some time so I will reply here later when my account password hopefully is recovered.
@Rowen Kendall it worked and I finally got access to my account again. I am so happy!
Thanks so much you saved my ass!
I would highly recommend using a disc of wire mesh. You attach it to a rod and push it down in the beaker, forcing eggshells down
The chemists french press
If you dry them out and peel off the membrane from inside the eggshell, you can crush them into a fine powder and it should go much smoother. The bonus there is that you're getting rid of proteins and other contaminants in the membrane that can slip into the mixture.
Digimon fan?
Very useful, i like these simple extraction/synthesis sort of video's, keep it up
And he kept

Nile,
I have just completed a repeat of your Calcium Acetate experiment. With a couple little changes to the procedure, I ended with just a little over 205g of semi dry product.
Thanks again for the pointers in the video. The net result came out very clean with no visible signs of contaminants. Now just to find a suitable wash before the final drying process.
With the lessons learned and this video, I think I have a good shot at a reasonably pure CaCl2.
Previous attempts have not yielded well as you know. Keep ya posted. Great Job~!

I would not recommend burning off the egg shells. In my experiments, it seems as though the calcium absorbs the contaminants during the burn off. Those extra contaminants are difficult to eliminate from the final product and also contributes to a foul odor during the reaction phase.
However, if you have a means to use very high heat it may work but you will end up with CaO instead.
Consider the following:
1-In about a 500ml of distilled water, boil the shells in broken down quarters. Let stand (to settle) and remove/filter out the floating and foamy material and try not to decant the shells into the filter. Save the water and repeat using the reclaimed water.
2- Reduce the shell size by another 25% boil, filter, and again don't decant the shells. Save the water.
3-In a grinder/blender ( I used a magic bullet ) decant the shells and about a cup of the filtered water from above into the container. Blend until the shells are reduced to "sand" like size. This step eliminates liberated Ca dust from entering the breathing environment.
4- Decant the entire milky and sandy product back into the beaker (or pot). With strong stirring add 10ml of Vinegar one drop at a time (to control reaction foaming) this step is to capture the Ca “milky dust” that would have otherwise be lost during filtering.
5- Filter the water leaving (sandy) shells behind. Save the water, and allow the water to cool.
6- Now rinse the remaining Ca "sand" with clean water (tap, distilled or RO), decanting and discarding anything that does not sink to the bottom. Repeat until rinse is clear. Then drain off all the water possible. Add back your filtered cooled (room temp) water from step 5 to your beaker/pot.
7-Perform the final reaction.
Note: Foaming can be somewhat controlled with strong stirring plate and/or by the addition of the acid in controlled drops. I have also tried a spritz of spray non-stick or a drop of veg oil with good results.
I have had my best results keeping the reaction in a CO2 environment. WARNING (do not allow reaction to compress CO2 and pressurize). Just in my experience, I believe that during the reaction the foam is responding to the outside air thus exacerbating foam production. In the CO2 environment, I have seen no more than ½” of foam at max. I bubble my reaction into a separate beaker of water and sodium bicarbonate solution. It is also serves as a good indicator when the reaction is complete or having an uncontrolled over reaction.
+PFM-Tech Thanks for the input! :)
I'm going to try to make this for my garden. Thanks bruv keep up the great work!!!
youre better off just buying a big giant sack of agricultural lime because it also has oher things like magnesium and trace metals but you get more...and...no hassle of making it....just DO NOT use hydrated lime
@@SimEon-jt3sr thank you.
Omg tysm tysm I’ve been searching every where for this
I would mention that the solution was colloidal because of leftover proteins and boiling it might push out and break apart the proteinsto form a white precipitate too :)
God bless you, helped with my chemistry homework once again
I've done this same reaction, with egg shells and vinegar. After the egg shells are good and dry, I put them in a blender and pulverize them. This avoids the "floating eggshells" problem, because they are a powder. Also, there is more surface area available to the vinegar, so I think it speeds up the reaction?
yes it does speed it up
that is an awesome reaction! love it! I am thinking on doing that same reaction at home
you also powder the eggshells to allow for a faster reaction but watch out for boil over
Egg shells are quite good source of CaCO3, but you really need them to be as clean as possible. Wouldn't it be easier to use chalk? (are there scools in other countries that still use chalkboards? 'cause in my country they are pretty much prevaling and I really don't know whether it's true to other countries)
And I'd really like to see the Iodine clock reaction and making pyridine. Thanks for the great work, Nile.
+Melody Williams Most chalk over here is CaSO4 and not CaCO3 unfortunately...
+Melody Williams AFAIK modern chalk for blackboards is not CaCO3 (because it's bad for the teacher's health to breath the dust in all day).
+Lars Veldscholte (Compizfox) +Nile Red I'll check this. Thanks for pointing it out. (sadly, the government of my country doesn't really care about health or teachers...)
+Melody Williams I see, you're Russian
+Nile Red hey buddy use few drops of IPA as anti-foam
For those who are impatient, I've found putting the wet calcium acetate in the oven at just below boiling for 20 minutes is enough to dry it without burning it.

I'd love to see the Calcium Acetate Jelly and Acetone videos.
Would heating the solution maybe help to speed up the reaction at the beginning?
Also is it possible that the couldiness when boiling the filtered solution is due to the decomposition of calcium bicarbonate that formed because of all the CO2 and excess of calciumcarbonate?
When you heat calciumbicarbonate in aqueous solution it turns into calciumcarbonate and drops out.
very helpful
Thx
Well, I tried this procedure and I had no idea boiling away acetic acid was so painful😭
That's why you never forget the water and use a fume hood properly, use good eye protection and have safety procedures ready xD
ikr, it was just *pain* , if i knew that it would be this bad i'd prepare
that’s why he reacts with the acetic acid being the limiting reagent-that way you’re just boiling off H2O
Hey I am a big fan of all your videos, and i wanted to do a couple of your experiments. including this one. i started to make the calcium acetate from eggshells, which was kind of a pain. i didnt really consider the tums bc they are expensive for what they are and honestly it sounds messy. I keep chickens though; and, i feed them oyster shell to give them their calcium. oyster shell is available in large bags for just a few of dollars at most feed stores. it seems to me that this would be an better starting material for making calcium acetate because it is easier than eggshells and purer and cheaper than tums. anyway, just a thought. let me know what you think and good look too with your work. its been a lot of fun to watch all of your videos.
extract nicotine from tobacco
+The wilderness survivors in 20 cigarrets are like 300mg of nicotine. It's just a waste of money and it wouldn t be efficient in any way.
if you grow your own tobacco and extract nicotine from green leaves. you can extract more. anyway it is for chemistry not for making money. I dont even smoke. it would only be cool how it'S doable
I know its not for money but like there is not very much nicotine in it and if he would try it out the yield would be very bad
he could anyway, he done it for cafeine
Doing it with loose tobacco would be much more economical.
"Started from the bottom now we here" -Eggshells
I would highly recommend adding backing soda to calcium acetate solution and then adding vinegar to the purified calcium carbonate because calcium carbonate can be easily cleaned since it doesn’t dissolve in water.
Hmmm
I was kinda surprised when you said that most kitchen vinegars are 5%, because at least in Hungary, most vinegars are either 10% or 20%, only things like apple cider vinegars and other natural vinegars are 5% here.
I dont know, but to me your beaker which is a bit broken at the top is your mascot xD
+SpektralJo So, if the chipped beaker is his mascot, then what would you call the melted and busted round-bottom flask? You know, the one from the Acetone synthesis? :)
I really like these videos about extracting things from natural sources, like the caffeine from tea/coffee ones. Not sure why, they just appeal.
Not much of a chemist, but would you perhaps not have had more success using a large flat tray, like a pyrex baking dish? Seems like this would have reduced the amount of stirring required, by increasing the surface area of the floaty layer of eggshells.
Amazing video quality! Did you get a new camera?
+JGPixl I got the Panasonic GH4 around christmas
Loving the new mic. What is it?
Cheapest source for Calcium carbonate seems to be "Garden Lime". You can buy it in a large 20kg bag.
Garden lime is basically just slightly dirty Calcium Carbonate. Would definitely be cheaper than buying that many eggs, and definitely cheaper than buying the anti-reflux medds.
Probably, but if you're eating several eggs daily, it's easy to start saving them up in a container with vinegar over time
We eat eggs every day got lots of shells that can be salvaged instead of buying an extra ingredient
You could freeze-concentrate the acetic acid to reduce the amount of water to be boiled off.
you should make some copper acetate then crystalize it. Absolutely stunning if done well!!
hello, I want to try this... how can we get the copper acetate from calcium acetate please?
Veerum Jokun put some vinegar and copper (be carefull with the penny because some have inside other over copper) add much of hidrogen peroxide and et voilà :D
You can also make it from CaOH and Vinegar. A acid base reaction will take place that creates the Calcium Acetate.
I'm assuming the foaming is mostly CO2, for example using a flash with a hose nipple on the top and put a stopper in the top and then the foam exits through the line out and into another vessel.
Hey :D cool video man! I've been waiting for months now for the methylamine HCL video to move to the "videos being edited" section but you still don't have a better pump for it xD Hopefully I can see it before I die^^
+Keta haha its because i need a good vacuum pump to do it but i dont have one yet :(
Thank you for this great video, wouldn’t be easier and faster to use a coffee grinder to grind the egg shells?
Too bad you couldn't use a French Press type device to keep the shells down.
this concept is much more better previous videos
Please do a video on STRONTIUM ALUMINATE. PLEASEE :D haha
The yellow tint may be from the presence of sulfur. Burning the egg shells first should get rid of that. Just do it outside or in a fume hood, since it will produce sulfur dioxide... Or collect it and use it to make acid :)
In germany supermarkets have cheap (a buck/250ml) 25% concentratet foodgrade vinnegar. I used that with calciumhydroxide. Doesn't foam at all. The latter can be obtained at a building supply store, ask for lime and say you want to use real, pure slaked lime. They should understand. Reading thouigh doesn't hurt.
Now that I can obtain this, I’m going to take Mario cosplay to a whole new level.
Just thought about that too, that's basically throwable fireballs!
Imma pull out this bad boy on the next snowball fight i get to lmao
Can I cite your channel in my lab report? I'm formatting it in APA, so should I use your channel name or should I give credit under a different name?
2:13 could be avoided by using a sieve to press it down or use a teasieve/teabag
If using eggshells or another organic source of CaCO3, like bonemeal or bones, or seashells, I suggest roasting the shells at high temperature for a longish time to burn off any organic material. This should probably be done outside one a grill since i'm sure the smell would be atrocious! I'd imagine a blowtorch would work as well.
For those looking for a pure form of CaCO3, might I suggest chalk sticks? Like the kind teachers use. A box is around 49 cents and it's almost pure CaCO3 except for a snall amount of binding agent.
I wonder how long you laid the Calcium acetate to dry and at what temp?
Hi, where do you buy/order your glassware? I buy mine from a local chemistry shop but they aren't so resistant and will easily break due to a small temperature change. Waiting for new videos :)
Nile, I've noticed from both you and other chemists that there are two types of morter/pestles. Is there a real difference between the ceramic and granite? ones?
Wanted to do this for camping where not allowed liquids but seems a bit a stretch camping at a festival 🤣
nice to know
Hi Nilered, I remember watching one of your videos where you explained a phenomena where mixing two liquids having different boiling points made the overall boiling point increase in respect to the higher boiling point of the original liquids. I can't find it any more (I must admit I have watched all your videos so I dont know where to start... I remember it was around acetid acid or the likes but i just rewatched all I could find) can you help me here please?
You can also use it in hydroponic solutions as a calcium source. Or just as a fertilizer.
We can actually get 25% vinegar for food use in most supermarkets in germany.
Didn't know it was a thing only here lol
"and my vinegar is on the right" Adam Ragusea collaboration when?
to separate it from the Tums, you would have to crush them up and dissolve then in water, perhaps with a little baking soda as well, then filter out the calcium carbonate, since the sugar and other chemicals are mostly water soluble, and only the carbonate is really insoluble. then it would just be a matter of following the steps in the video here with that calcium carbonate. if the sugar doesn't want to separate from the carbonate for whatever reason, then dissolve it in the acid, and add baking soda to precipitate out calcium carbonate, then filter and wash the carbonate to get calcium carbonate by itself. then just do the process shown in this video to get the acetate.
u should make polyvinyl alcohol
A solution for the number of names may be to split the donators between the number of videos you release each month.
Eggshell will never be a pure source of calcium, as it consists of a protein matrix as well. You could try to calcine it away or use piranha solution, but it's way easier to use crushed limestone. Still not pure, but the impurities aren't organic. Also, 45% vinegar is available from Walmart and will make the evaporation step way faster, as would applying a vacuum.
I would highly suggest using a larger container! 😂You should write that in capital letters onto your labs wall.
Surely a coffee plunger type setup would be ideal for keeping the eggshells submerged
Would it be effective to use a blender?
We love your videos -- especially my daughter (4 yo). Quick question: What if instead of egg shells (CaCO3) you used Gypsum (CaSO4) against the acetic acid to produce the Calcium Acetate. Woops, that creates sulfuric acid, doesn't it? hahaha (I literally just learned that.) We have a ton of CaSO4 here left over from other work we did. Oh well, we'll give it a try. Best wishes!
The sulfate ion has a higher reactivity than an acetate ion. It would therefore form an unfavorable equilibrium so it likely wont work/wont work well. If heated high it might push it forward but as soon as you cool it down, then it will reverse. You could use cheap soda ash from the super market to react with the gypsum to make usable sodium carbonate. Since gypsum is rather insoluble, you might need to boil the soda ash with the gypsum for it to react.
I was a bit spooked when it precipitated out of solution, thought it was proteins from the egg coming out of solution and not the actual Calcium Acetate itself. Going to let my batch dry overnight. I'm planning to test the isolated stuff as part of a hydroponic fertilizer blend instead of just the ions in a solution.
Nile can you do a synthesis of nitro methane? it would be a very useful video for me and some ppl I know who drag race. big fan btw your videos are addictive.
Reagent grade calcium acetate is also yellowish in solution, its a little odd but I think that is just how it is
When would you do the flamming jelly and acetone vid?
+Saikit Tang I already filmed it, so it is just a matter of editing it
Can you make Calcium Acetate with limestone or calcite crystals? I can get both from natural sources in my area.
So...where is the part where you make the flammable jelly?
kindly guide??? mean we should stir for 12 hours continuously or just soak crushed ground eggs in vinegar for 12 hours and after this just stir more... will it work or i will have to stir continously when it ends bubbling add more shell while stiring.
You could use diluted acetic acid if you can’t find the cleaning vinegar.
Success!!!! I was finally able to make the jelly!. The first try failed because I used 70 % alcohol. The second time I used 91% alcohol and voilà
I'm shocked that so much was left after the water evaporated. From a transparent liquid to that powder, thats crazy to me.
could you make a video of the jelly that you mentioned in the video? I think I actually made some calcium acetate, and I want to convert it into the jelly you mentioned in this movie.
+Jarom Schafer I posted that video yesterday! :)
If you were had the time could you just leave the filtered solution in a sunny place to evaporate? That would keep it from burning.
Can you make calcium hypochlorite without expensive chemicals? Like using things the average person might already have, such as eggshells?
Hello, in the manufacture of calcium carbide, is it possible to use any type of coal or exclusively coke? Thank you
I don't know if there's an equivalent tool in chemistry, but would something like a French Press have helped with your floating eggshells issues? You could have put them in, pressed it down just far enough so they're all submerged, and then also pressed it down the whole way as your filtering step (or at least a precursor to it if the mesh doesn't do as good of a job as the filter paper).
Or would the material of the screen have contaminated your reaction?
+DeDraconis This French Press thing is also used for coffee right? If it is made out of steel or something like that then it may be dissolved by the Acetic acid (only slightly but you would get iron acetate in your product), if you would use plastic or any other material that can't be dissolved by acetic acid then it should be fine.
I wonder if you could have offset the bubbling a bit by putting the eggshells in a cloth teabag.
I made some experiment for my follower on instagram, the same things you make , how I can purify my calcium acetate? If i put the solution in the acetone the calcium acetate precipitate right? Or what I can do ?
Would you be wiling to do any experiments involving Uranium? Perhaps making Uranyl Nitrate?
+Anti Photon If only i could easily just get uranium. Also, radioactivity is scary!
+Nile Red Uranyl acetate is cheap from Ebay, when heated it decomposes into uranium oxides
It was a good video , we do have lots of egg shells
Do u have to sterilize the shells first , and pls give back the ratio of water to shells
Thank you
For april 1st I had hoped you had done a normal video but with a laugh track.
+Povl Besser I wish i did an aprils fools video
2:20 Where's your cool magneto stirrer? :)
Stefan Reich I think it wouldn't really help, since the eggshells are floating on the surface
What about refluxing eggshell powder with aqueous NaOH to get rid of (I hope) most of the amino acids and maybe some other stuff. Than separate the CaOH and react it with acetic acid to produce a higher purity product for the preparation of acetone.
Greetings. I was wondering once you have your calcium carbonate dissolved in Acetic acid must you boil the solution to have the calcium acetate drop out or if you could just evaporate all the water using a evaporator?
both work, it just takes forever
You should invest $10.00 for a cheap electric coffee grinder. It really helps to powder many chemicals that would normally take quite a while with a mortar and pestle.
Thanks and thumbs up.
One more video and we can learn how to make chloroform from scratch in case of apocalypse. Show us how to make vinegar :)

Do the Acetone!
Hey man, I like your videos keep up the great work!
Maybe a weird question but do you know how I can crush apple seeds till it becomes powdery?
I'm assuming you want to extract cyanide compounds from them?
First of all, there is very little cyanide in Apple seeds, and you would need a large amount to do any sort of valuable extraction. Also, the cyanide is tied up in cyanogenic glycosides, a pair of molecules which must react together to form the actual toxic compound (they are normally combined when you chew them up in your saliva), so I don't know whether they would still become active through powdering them. That being said, is dry the apple seeds on a cookie tray in the oven at a low temperature and then just use a coffee grinder :)
And I'm sure I don't need to tell you how dangerous that would be
+Samuel Maybe just dry it in the oven and then crush them up?
Will it blend?
Wouldn't it have been better to dry the eggshells, then grind them up using a mortar and pestle? Maybe they wouldn't have floated so much since it would be more like a powder.
+bobear7 That is true. A powder would have definitely worked better. I really wanted to make this method "barebones" in terms of equipment
Hello, I really enjoyed the video. Could you make a video about "making calcium chloride" please?
Mix the eggshell with some HCL, hydrochloric acid, be careful
Do you think the process of dissolving the egg shells would've gone faster if you had grinded the shells more finely with a stone mortar?
of course - more surface area, reaction would have been shorter by a lot. except he probably didn't do that because it would have produced a lot more CO2 in that amount of time and possibly overflow his beakers.
Hello, I would like to know that, cant we use the white edible vinegar than this cleaning vinegar please?
Where can I get the tiny mixing capsules and are they expensive?
Hi I'm a student I did the same thing but I did it with crushed seashells
Hi Nile Red is this possible to make formaldehyde in thermal decomposition of calcium formate?
Where do you buy your chemistry apparatus?
I used seashells, and instead of boiling, I added ethanol to try and get it to crash out of solution.
Are egg shells supposed to dissolve and disappear completely? For me looks would take years, or is the procedure completed when co2 stopped popping, even with shells still intact?
Can you also do this with snail shells and clam and limpet shells?
sure
uuuh
Even dead coral would work, I know that coral polyps make their skeletons out of CaCo3...
This yields cleaner calcium acetate. I made calcium acetate using that.
I can find calcite crystals in my area. Just some hunting around road cuts will find both calcite and gypsum crystals. I betyou can make calcium acetate out of either. The calcite crystals that I have gathered before are very clear. Maybe they are very pure?
Have you considered working with experimental graphene?
Hey Nile do you have a research that discusses about that ? Please reply ASAP
