Hello everyone. Today we will grow some crystals, again. As in the previous video, I will try to describe the whole process of growing the crystals to you.
First, we need to choose the material of which we will grow the crystal. Essentially, practically any substance is suitable for crystal growth.
For example: protein crystals, crystals of iodine, metals crystals. Even air can be turned into a crystal when it is cooled to a certain temperature.
For normal conditions, the best suited are inorganic salts. And for this time I will grow crystals of potassium alum.
However, from personal experience, I would say that copper sulfate is the best substance for growing crystals at home. Table salt is not the best material. Bluestone is easier to buy and you will get beautiful blue crystals using it.
To begin, let's take any vessel and pour there some of our salt. Next, pour hot water into the vessel and keep adding salt until it is no longer dissolvable.
In this case, we get a saturated solution. Be sure to add hot water, to be safe with the proportions.
Different salts have their own solubility curves.
Solubility curve is a measure of how many grams of the salt can be dissolved in a 100 ml of water at a certain temperature.
Also, for all of the salts the information is different. Once we have prepared our saturated salt solution, it has to be filtered while it is still hot.
Filtering is not required. However, if you buy the chemicals in a garden shop, not in a special shop, the solution must be thoroughly cleaned from possible impurities.
I would still recommend to initially use pure chemicals.
After the filtration, let's leave our glass for a few days to let the crystals form.
Crystals form as a result of the change in solubility of salts in the water when the temprature changes. Excess crystals, which cannot be dissolved in the solution, they fall to the bottom of the cup.
After a day we may notice that beautiful crystals were formed at the bottom of the beaker. These crystals will be used as seeds.
Seed is a small crystal that is immersed into the solution, which will continue to grow new layers of a crystal on top of it. Now let's merge the solution into another beaker.
Next, choose the most beautiful and large crystal from the mass of crystals that were formed on the bottom of the cup, or the one that is easiest to tie on a thread. I could also advise here to use a thin fishing line instead of threads.
Once we have tied a crystal to a beaker we pour our saturated solution of salt back there. You can tie a thread to a regular pencil and hung a crystal in a glass using it.
However, for myself I've decided to use a system, in which the glass will be protected from dust. I think this is not necessary. At the moment we can only wait for the crystal to grow.
Over the time of the growth of the crystal, it will become bigger and bigger. This occurs because the water from the solution will gradually evaporate, thereby increasing the concentration of the solution.
Since we have a solubility curve, we can learn that the excess material that cannot be dissolved must go somewhere. And this is the substance that forms our single crystal.
If we had not hung the seed, the crystals would have started to fall anywhere - on the bottom or on the walls of the beaker. And one more thing to mention!
During the process of crystals growing, liquid from the cup will gradually evaporate, and therefore the crystals grow. But, that's also a problem.
During the evaporation of liquid it comes to a certain time when there won't be enough solution in the cup anymore, and the further growth of the crystal will be impossible.
To solve this, once a month or once in every two weeks it is necessary to add a saturated solution into the beaker. The saturated solution must be prepared the same way as it was before, by adding salt into a hot water.
However, you should not add a warm solution. The saturated solution should be the same temperature as the growing crystal.
Also, once a month or once every two weeks, I recommend filtering solution to maintain its cleanliness.
Over time, in the solution some specks or other dirt might occur, which can screw up the crystal.
Over time, my crystals from potassium alum become bigger.
As you can see, they have acquired a very interesting form. And now, after about 3 months, I have grown two beautiful crystal of potassium alum. Facebook: / thoisoi2

"I invite you to enjoy the beauty of my crystals." Ah geeze, what a sweet person.
Bahahaha I can't stop laughing. There is something deranged about this comment and its humor.
+nvshd I don't understand why you say that? He sounds like a kind person and it made me smile.
+Gin S. This has got to be one of the best youtube comments I've ever read, very nicely said. :)
Gin S. Bad widow b,b,b,b lanat ho👅💔
is a kind of bob ross. ..
"And now, Ladies and Gentlemen, I invite you to enjoy the beauty of my crystals, with no further comments."
-Awesome.
yeah
U are one of the first people who led me into crystal growing, now I'm pretty great at it, 3 years of experience now, maybe more!
Just wanted to say thanks :)
I just started yesterday, any tips?
Use distilled water, use fishing line to tie the crystal up to avoid crystals growing on the thread, cover it up because dust will mess with the growth.The best place to grow crystals fast is in a warm and dry environment. To mix the crystal solution, I use a glass rod from a chemistry set. Sorry, I’m a bit rusty, it’s been a few months since I’ve grown crystals.
Oh, and one thing, NEVER COMBINE ANY CHEMICALS WITHOUT LOOKING AT THEIR FORMULAS FIRST, I once tried to combine sodium tetra-borate with ammonium di hydrogen phosphate. It made a gas cloud comprised of ammonia. I was poisoned and had a really bad day.
@@user-mh2bw4hu3o well I only had aluminum powder from a really bad DIY kit and it seems like it's kind of doing something? It's really hard to tell because I don't know what is to be expected lol. Thank you for the tips, the fishing mine is a really good idea because I was kind of worried about having regular string show.
Despite your strong accent, the way you speak is easy to understand, kudos.
This video was very informational! One of the best I have seen.
Christopher Daly II honestly I have to read the description
couldn't you theoretically grow a crystal to a massive scale this way given enough time? imagine growing one big enough to sit on, you'd likely need a very large container for it to grow in but that would be very interesting in its own way.
umm. let me know if you end up doing that lol. I'd like one
Cool idea but think how heavy a chair made like this would weigh.😊
A crystal throne, nice
At least up to a 5 gallon bucket size!!! lol....🤔😆😆
I love the careful application of procedure you used to get such beautiful results. I am a teacher and will attempt to grow crystals for my budding Earth Scientists over the next couple of months. Thanks for the inspiration!
anyone reminded of shrek 2 with that music?
YES OMG
Great video. Very informative. I had NO problem with understanding your English. In fact , it was better than some of my American born friends. People hear what they want to hear. Some people are more interested in your accent , than what you are saying.
AGAIN ; GREAT video. I am subscribing to your channel and looking forward to more videos on this subject.
You're full of shit!
You understood all of that jibberish? Please TRANSLATE for the rest of us!

Bob Barker says the one who is full of shit.¬_¬
after doing this myself id would suggest using clear fishing line so you don't get some string in the center, it ruins the beauty. and instead of clear nail polish, try clear spray paint, you get a much smoother coating if you do.
OMG You really are great at crystal growing and the no comment part shows appreciation. Your amazing
YES! Make more videos. Many of your videos are so unique to RUclips they are almost exclusively on your channel. I love seeing you pop up in my sub box
I found a way to simplify growing alum crystals. Get a spool of "invisible" or transparent thread. This thread in reality is very fine monofilament. Make some supersaturated alum solution. Dip the end of the thread into the solution then remove and let dry a few minutes. This will cause tiny crystal seeds to form on the thread. Put the thread back into the solution. By next morning you should see visible crystals on the thread. Since the thread is smooth you can slide the crystals up and down the thread. Find a few promising seed crystals and separate them and space them out a bit. Put the thread back in and watch the crystals grow. After a few days discard any crystals that aren't growing regularly. If you have a tall container you can grow multiple crystals at once but if your goal is one large symmetric crystal you can remove all but the best crystal. When it is time to harvest the crystal you can simply pull the thread out of the crystal so you won't have visible thread.
Hello ! First, thanks for the vid, I used it to create my own Crystals and here I am to share the results. The advices are correct except one: filtering IS indeed required.I understand why you mean if this is absolutely certain that the water and the Salts are pure BUT in most cases it is not and plus, you have no guarantee unless you check. During the first try, I did not filter the solution. I obtained huge crystals which could not be used, then I obtained a lot of agglomerates of Crystals around my seed during the precipitation. During the second try, I did filter and the results was absolutely perfect. I know this is an old video and again, I appraise your job, so please keep in mind this is only to share experience and for the people who will read the comments afterwards. Thanks and I hope the work is keeping up!
how long does it take to get crystals the size of a pingpong ball? and can you use seasalt too? do you need to keep filtering every few weeks>?
I am not the author but I can share with you an answer since I have been making my own crystal for more than a month now. You definitely need to keep filtering the solution BEFORE putting the gem in and yes, every few weeks too. Also, the reason is that at some point, the gem will stop growing and crystals will precipitate at the bottom of the glass (don't know the name in English). So I also make the whole solution (without the gem) dissolute again before letting it get cold and putting the gem back asap.
In a word: it is not a passive process. I thought it at first but the results were very far from my expectations. Now the crystal is perfect and each edge is more than 1 cm edge.
I think you can go faster, the reason is that since I am pretty busy, even though my crystal has not been growing for a week or two, I take some time before renewing the solution.
So it is not a fast process either, but you can get pretty satisfying results in a month. The key factor is to filter the solution and to choose the gem carefully, then let everything rest as it is.
Finally, about salt crystals : yes you can make a crystal as well, actually you can make a crystal out of any ionic solution such as sulfate copper (you will have very blue color by the way). Yet each crystal form is a characteristic from the atoms of the crystal, so for example, a alum salt monocrystal is an octaedra and a salt monocrystal is a cube.
I hope this was consistent enough. Please let us know is you try out :).
Hey man this video was amazing and I cant wait to try this myself! Also I adore your voice :D
For the 3 month of work, you deserve another like! GL in your other videos!
I absolutely love your channel.
I think it's funny how many people can't understand him well. I don't have any problems understanding him.
Curtis Dorris I'm Egyptian and I can understand Arabic and English 😊✌
I'm from Brazil and honestly I can understand his english perfectly fine, people just like to whine.
Curtis Dorris some people don't hear well, like me.
He has a Russian accent.
@@nourwesam same here yasta
Woooow man,you rule :D keep up the good work that crystals are so beautiful *o*
Love your videos! I can't wait to try growing a single crystal.
Looks fantastic. Great video too. Well done. I enjoyed the beauty of your crystals in the end too.
Beautiful!! I hope My granddaughter and I can make crystals as beautiful as these - wish us luck!
All done in English for our viewing and pleasure.
Thank you, what a wonderful video
i was supposed to do this for chemistry project, my teacher did explained the process but i had some doubt, now its all clear to me
I love your videos! And I love how you include your cat! Next time I get paid, I'm going to look into crystal growing 😊
I actually made one and it came out beautifully, I loved how my crystal came out so much, I decied to make more of them. 🌹🎀💎🎀🌹😘
The diamond is going to represent the Crystal today, so uhmmm
.......
.......
Yeah
Love your videos man :) Also am I the only one who thought about some crazy radioactive crystals after he said that you can grow it out of pretty much everything? haha :D
Oh, you again.
YEAAAAA BOIIII ANOTHER GREAT SCIENCE VIDEOOOOO
Wonderful Information Thoisoi2!
Interesting video. Ever tried to grow a crystal in an certain frequency of sound? I wonder if that effects the shape of the crystal. Water changes at different frequency an I am curious if this would work to when growing one...
Thank you for this video - I liked the clear explanation and wonderful visuals. It is an inspiration to start growing my own at home! What do you use to filter the saturated solution, and could you suggest any alternatives if I cannot find what you are using? Thanks in advance!
It looked like he was using a paper towel, but maybe coffee filters would work. Note: I haven't tested that myself, but will be trying soon. 💎✌️😎
Great video man! Love it!
I thoroughly enjoyed the beauty of your Chrystals
I think if you want to reduce the "ugliness" of the thread inside, you can use nylon strings or other strings that are transparent.
i wonder if you could use a colored crystal as a seed for a clear crystal and get a large crystal with a colored core
Depends on the material. Some materials exhibit strict structure in their solids and therefor need an almost perfect crystal to seed, while some materials are very forgiving and take anything they can to grow crystals on. It could be possible but any 2 different colored salts probably wont give that effect. Best would be if you could find salts with the same metal in them that have different colors, though rare, it would probably be the best since metals almost always have similar structure in all their salts.
That's an awesome idea! It might not work on the first try but if the seed does not resolve you might wind up with a multi colored cluster! Such a cool idea, really makes me want to try it. Thanks!

Vkgjillo Kjgjilop What?
LOVE your guys accent, if you think about it, an accent is just a dialect
we live on the same planet and your expression of the alphabet causes your english to sound different
the same is true about people a few states away, or half-way around the world
Congratulations on your new crystal.
So it must be filtered every couple weeks and a new solution is made to keep the Crystal growing
Im wondering, are these crystals hard enough to polish and give it a better shape or are they too fragile? If its possible il make a few of different colors and put them in a glass case at my office.
+Goku Nimbus Seconded on that question.
Depends on what you're polishing them with. If you take it to a belt sander, probably gonna break it, if you hand sand you may be fine. Understand that because you use nail polish to protect the crystal, it will eat the top layer of the crystal. So you may polish it lightly.
Maybe a piece of damp cloth can be use to polish the crystal since it is soluble in water.
I always love an look forward to ur growing crystal videos!
SIMPLY BEAUTIFUL!!!
SUBSCRIBED, no hesitation. After watching your videos, you're amazing. whats the intro song btw?
SpartinPlays Eels - I need some sleep
Is there a way to shape the crystal the way you want?
nati tzemou it honestly depends on the solution-- if you get different solutions and look up their "shape" or "crystal structure" it'll tell you the shape of he crystal it'll make :)
I can't wait that long
This was awesome Th2. Thanks!!
i think your english is hilarious!
but its understandable and your videos are cool,
keep it up!
I like how he puts extra emphasis on crystal and certain other words. It sounds so odd and funny
Very cool video! I like it! I do have a question though. Those crystals are in a very pretty shape, but is there a way that I can make those crystals in a pillar shape like a pencil? Or any other unique shape?
Every compound crystal has a shape..you can't change DNA
The crystal shape depends on the element or compound you're working with. Change the chemical, change the shape. 💎
I love your accent man!!!!
Thanks! Want to give this to a special person on a date she hopefully won't forget! :)
How much time does it take for these crystals to form on the bottom of the container? I am currently growing crystals of KAl(SO4)2 but after a day no crystals grew even though the solution was saturated.
KusKusPL in one video he said it took about 2 months
I have to ask!! (I don't know if you will answer..) What do you do with the thread after the crystal is big enough?? :D
You should cut the thread with scissors
This is the best comment that I've seen all day...
I can't use a knife?
Thoisoi2 - Chemical Experiments! What about the thread inside the crystal..??
you could use a fishing thread as well.
quarentine crystal growing. Great idea for me to sray home
I actually did this !! I’m going to make videos for it soon! I used alum potassium sulfate (alum, KAI(SO4)2) and monoammonium phosphate (NH4H2PO4) in multiple different expirments
I really need to learn mad scientist language because this guy teach us really amazing things but Damn it is hard to understand unless someone adds English subs
Hahaha I like this guy
now you can play d&d with this d8!
Awesome crystal!
I LOVE this channel! 😁
Thoisoi2, can you please tell the name and author of the LAST SONG of this video? It begins on 6:12. Tks.!!
I'd like to know also.... cool & smooth soundtrack that is :)
Very coool, is there any way to do this without using string? It is still visible inside the crystal
you can use telepathy
What i wondered about is. It may be better to use a very thin transparent fishing string instead and just glew it to the seed crystal with a tiny drop of super glue. That should be invisible and still hold as good as the string he used. (the word the joker above me searched for was telekinesis)
***** You probably meant "telekinesis" :)
London Averill Do you know how to spell because it don't look like it. :/
Fishing line it will be less visable
Its funny the part when he shakes the solution, as the video is speeded up it look like the flash is shaling it haha, nice video!
Thank you for sharing this awesome video
you sound a bit like Dexter from Dexter's Laboratory
what would happen when you would grow one crystal type on top of another.. and make *crystal layers*?

have you thought in making a blue crystal grow for a whole year?
I think it would eventually overwhelm his container if it wasn't big enough. Besides, who needs giant crystals? :) 2 months are enough
It is looking amazing
Great Video presentation!
how about to grow a crystal on an insect skeleton (cockroach for example) ?
*****
>Insects don't have bones, though ;)
nevertheless they have skeletons
I was thinking about that also
Vladimir Vladimirvladimir I know of an artist who does that.
how do you make the thread disappear inside of the crystal?
He just let them inside 5:49 , 6:15
so sad..i want it to be fully transparent :'(
yess...nice idea..i was thinking bout that but the fishing threads i found were thick..kind of for bigger fish..
if you want thinner fishing lines go to a fly fishing store, there you can some
thanks
It's like been Father Nature. Great work.
THANK YOU SO MUCH FOR ALL YOUR HARD WORK FOR US TO SEE.
JEHOVA GOD BLESS YOU ALWAYS Thoisoi2 - Chemical Experiments!
yeah cause I totally have some potassium alum just sitting around my house
Sometimes used for pickling. Can also be obtained at craft and hobby shops for various uses like making crystals.

The kitty cat is s cuuuute but the crystals are just just so cool and empressing
Thank you for this great video.
Your videos are soo good
That was so cool I am going to try it
Thank you. LOVE your kitty!!!!!!
Very great video! Thank you so much :)
This is so cool!
I cant understand a word but i love the experiments XD
Your accent is awesome.
You said to make sure not to add warmer new solution to the old one to avoid increasing the solubility of the salt by increasing the temperature. That I understand.
But if decreasing the temperature decreases the solubility (and so increase crystal deposition), why don't we just stick it in the fridge or something? Why does cold badly affect the crystal? (You also said to avoid the extremes of temperatures)
This was awesome I will love to see different color ones
Those are awesome!
I understand his language and sometime I feel like he slowly go back to his first language with a really smooth transition, not a hater
Dude, That was awesome!! I cannot believe my eyes! I do want to know if I can do this with regular salt.
Pretty nice video, good job ;) Have you ever thought about snapping a pic or two of the crystals you made and uploading the photos to Wikipedia (and perhaps linking them to the article about that particular chemical)?
Everything was nice, so I decided to watch this video, and because of the music at the beginning I'm sad now. :') I love this song.
I found that tablesalt is actually a excelent crystal for growing at home, it is super cheap and easy to get often around €0,5 to €0,7 per kg or sometimes even less, it is cheaper than sugar by far and yet it is a lot harder to mess up than making sugar crystals. the crystals they grow are also super nice and unique since it is kind of like bismuth crystals but then more square rather than maze like you get crystals like cubes with often hollow holes in them also in cube shapes and sometimes more to the edge so it is kind of like a C. to make them I just oversaturated the water while warm, even though this temperature barely has a difference so hot water isn't needed. I had oversaturated it so much there was a decent layer staying on the floor. then I put a small long wooden stick in it, I also put some glue with extra salt on one side, the part with glue and salt eventually grew the fastest. it takes longer because now after around half a week the crystals are still super small mostly other than at the place where the glue with salt was. but since it is super cheap and simple(I didn't use any filtering and didn't cover or clean it, I only put a bag below it since sometimes you get a rain of salt around the jar(some salts). so it might be worth just making a jar with it and setting it aside. perhaps if you think about it resaturate the liquid so it grows faster. but crystals grown from ordinairy tablesalt look really nice and mostly really strange compared to most other crystals, mostly since it also has inverse geometry as in that the geometry doesn't only tell it where to expand, but also where to hollow, crystals growing hollow places like that aren't as common and so really nice.
beautiful thank you for teaching
thoisoi, you are the best, also it was easier to understand because of that bottle... siran hlinito draselny... zaujimalo by ma kolko slo akov tu je:D
I LOVE HIS ACCENT :-D
Thank You for the info brilliant channel
Thank you for the video, sir. Your English is excellent and clear. Those people who can't understand you have very rigid minds. Just a bit of flexibility and you'll get the hang of it. Try it, you'll like it, and you'll be able to communicate to a wider world.
