I just watched this man microwave sugar and let it sit out for a week
goals
I'm a science teacher and I let my students make 5 sticks each for them selves and it was so much fun!
There probably so happy they got to get 5😆
When you allow the string to dry, you are removing the water, leaving behind just the sugar stuck to the string. Since the solution is super-saturated, the sugar wants to come out but has nothing to stick to, in order to from crystals. Once you put the string with the small crystals back in, the sugar is able to stick to that in order to come out of the solution, and the new crystals provide more and more points for sugar molecules to "stick."
After the solution cools down it becomes supersaterated from the high concentration of sugar and the fact that high energy(temp) = high solubility and low energy(temp) = low solubility of a substance in a solute. However the slow temp change allows for the extra sugar to stay in the water then it only needs something to start the crystallization. At least I think thats close.
Do we still need adult supervision if we are 18 years old?
Spinoblood21 have fun
What is the number to poison control?
You might need adult supervision if you cannot answer that question
No
If you have to ask, then yes.
So for three cups of sugar, you get one little string of rock candy - seems a bit of a waste.
We'll you can do it more
Ryan Wen well*
You can do more, you can re heat the mix and do more
reuse it
Drink the sugar water
It's because by putting in way more sugar than there is water, you made a solution that is super saturated with sugar. Normally if you mix in that much sugar and water together, the sugar wont dissolve, but by heating the water to boiling point, there is much more room for extra sugar. When the mixture cools it needs to get rid of the sugar that super saturated the solution by forming crystals. It forms crystals on the string because you coated it in the solution and let it dry for a bit, that way you made seed crystals on the string that would actually cause sugar to grow mostly from the string, but it will also form on the bottom of the jar because likely there will be small amounts of undissolved sugar crystals that will also act as seed crystals
By heating the water, you allow it to become supersaturated with sugar, and the dried string acts as a catalyst to the sugar, allowing it to unsaturate and for the crystals
I does that because you desolved the suger in the microwave and when you left it it crystallizes again but in a diffrent
So I’m 29 now and just had a “do you remember rock candy?” moment with my boyfriend. I first clicked another video with over 6 million likes. Got bored 5 seconds in, came here, and was not disappointed.
Easy instructions. Simple setup. No frills. Just science.
Ur tutorials are soooo much easier than other vids where they talk and confuse you. Just the steps, and fast forwarding and ur done :D
A little tip try making it into shapes with pipe cleaners that's what I used in science camp
The sugar solution is supersaturated. The string that contains sugar on it causes the solution to crystallize.
We are learning in science that some rocks take time to crystalize so it makes it different from the other and we did this on Friday!
I've made these before! Yes they're edible! Taste good but just sugar. Maybe add some flavouring mint or something :)
because the string is warmer then the cooled solution. That's why the crystals are forming..
the suger is a form of cystal when mixed with water they combine (like stalegtites in a cave) and can become a solid form with the right stimuly (the string)
The candy is formed because the atoms of sugar want to kiss the yarn, but they can't go!
What’s Going On?
• Why does the string need to be soaked and then dried?
The string will provide the surface on which the crystals will grow. As water evaporates from the string, small crystals of sugar will encrust the string. These tiny seed crystals provide starting points for larger crystals. Future growth will be concentrated around these points.
• What makes the crystals grow?
Two different methods will contribute to the growth of the crystals on the string. You have created a supersaturated solution by first heating a saturated sugar solution (a solution in which no more sugar can dissolve at a particular temperature) and then allowing it to cool. A supersaturated solution is unstable-it contains more solute (in this case, sugar) than can stay in a liquid form-so the sugar will come out of solution, forming what's called a precipitate. This method is called precipitation.
The other is evaporation-as time passes, the water will evaporate slowly from the solution. As the water evaporates, the solution becomes more saturated and sugar molecules will continue to come out of the solution and collect on the seed crystals on the string. The rock candy crystals grow molecule by molecule. Your finished rock candy will be made up of about a quadrillion (1,000,000,000,000,000) molecules attached to the string.
There's too much sucrose that could crystallization in a week, because mostly separated into fructose and glucose. Back again to normal when something interrupted.
I know!!!! It rots!!!!!!
Lol, no!! The string acts as a crystal seed. In other words, it is something that the sugar can start crystallizing on under the right conditions.
arthurthegreat it has a sarcasm side...nerd
arthurthegreat also the fact that it gets too concentrated and has to deposit(it being the sugar
No your wrong. As the water evaporates, it leaves sugar behind which dew to slow evaporation of water the crystals form
TheInsanenoobs there is not enought water evaporating to make a diference however the solubility of a solid is proportional to the temperature. therefore, you can get a lot of sugar in the water when its hot but a it cools down it begins to precipitate. then the string acting as a catalyst, the crystals grow on it.

i read that the blue meth in breaking bad is actually crushed blue rock candy. that is the main reason i love this vid
The sugar dries and instead of going to the bottom it stays on the string and in a week it should of mostly got on the string
Maybe bits the shugar that gets allí moldes up and creates that rock hard etible candy struckure !
Sort of like honey, since it's thick like honey, it crystalises as it sits, so when you take the string out, it will have the crystals on it, only larger, i think.
Our liquid is supersaturated. It has too much sugar. Theoreticallly, we couldn't dissolve that much sugar in one cup of water. But we were cheating - we used high temperature (hot water could "take" more sugar than cold). When our syrup cooled down, water was supersaturated - it was just a matter of time, sugar had to crystallize and it crystallized on our string!
Bruh my teacher told the class to do this project 😀
yo same
I am in the process of doing this with 5 different kinds of sugar, as a science fair experiment. As I made the solutions, I dipped a wooden skewer in the solution and rolled it in the respective sugar. I then poured the solution into a glass jar and put the seeded skewer in the solution. However, I didn't not wait for the solution to cool...do you think this will still allow the crystals to grow?
No it wont. Me being impatient I didnt wait for the solution to cool completly and went ahead and put my sticks in, I check on them about 5 days later and all of the liquid fused together making one big sticky mess.
+Joan E i think i just got an idea for for my science fair project
all i need is a bunch of sugar. and teacher approval
and patience
@@kiwivvv How did the science fair project go?
The candy uses principles of crystal formation and sedimentation to form giant sucrose crystals. Included seeded sticks provide the perfect surface on which the crystals can form, and the end result is enormous and delicious sucrose crystals on a stick. They're just like the rock candy you can get at stores!
Yay for supersaturated solutions!
Do I need a rock
Depends how you want it
😂
its play time with my cousin
he meant it as a joke
It's not required but it just looks cool
No hate, but the green water thumbnail makes it look like a over-spikey pickle XD
Thank you for showing you can use a microwave
No coating the string with sugar? I was always told to roll the string in sugar. It gives the rock candy something to hold onto
I guess it crystallises
I did one of these for a school project but my jar had gotten completely crystallized any one know why?
I guess too much sugar
Is it because the suger hydrates when it is heated?
Say i have a question in regards of making multiplies amount of candy. Is it possible to reuse the candy Syrup solution to make more or would i have to repeat the process over again?.
Does it have to be cane sugar?
Can flavoring be added like citrus or vanilla?
can you use any kind of sugar
I've finally seen your face
Because you used more than enough sugar .. It couldn't desolve in the water
If i did this i would stop after step 2 and for step 3 i would go to town on it
nice glasses and you are good at showing step by step videos so you earn a subscriber
can you use each batch of solution for multiple rock candies?
sick - why is colouring needed???
Draalo it isn't it's just for the colouring ;)
Draalo if you wanted you could just make it without food colouring and it would be a transparent white rock candy ;) Hope I helped even though it's a couple years later
Is it supersaturation?
The form on the string because its the only part that was dipped in the solution
I tried this, and when I went to eat it the crystals fell off :/
You should make 2 for back up
Hi. Nice video. Would you mind if I use just a few seconds of your rock candy making video for a different video? It has nothing to do with cooking or candy. My video is about a genetic illness where molecules in blood precipitate into long strands. The best example I can think of is how rock candy forms crystals from a solution. I will probably put it on RUclips also in the near future after I set up a channel. I will cite you and your page if you do not mind. Let me know. I am pushed for time and have to send the finished video to my mom tomorrow for a health fair. I am not positive I will use the video but I wanted to ask just in case I do. I have asked a few others the same question to cover my bases, so I would probably go with the first positive reply I receive. Thanks.
Because the sugar hangs on the string
I made it and I ate it...I was delicious
would it work if i just heated up water in a coffee pot and poured it into the sugar??
Water starts to evaporate on the string, causing pure sugar crystals to form on the string.
The sugar it's like salt crystals but sugar
becuase the string is the best nuclear ion point i. the jar.
thank you so much for this video this is my #1 candy in the world
How long does this take to crystallize?? A few weeks? Or less?
Is it okay if I put worm water?
I don't have a microwave.
That is the amount of sugar I take when eating candy?!?
i was hoping id see how he looked thru the reflection on the microwave, but he even positioned himself perfectly so the camera won't see him
how long do you have to let the string dry on the waxed paper
5 years 😛 Ur welcome
Instead of setup 3 I drank the sugar water....
The sugar cristalizes on the string.
The science of crystallisation :D
it looks like a green ebi tempura-
Spinoblood Especially if your 18
Crystallization
It's easier and cheaper make it with salt because you don't need to warm it in microwave.
Then it wouldn't be candy. It would just be a huge chunk of salt
Eldre Kurt Maraan
Yes, it wouldn't be candy, you can't eat it :)
It would be a huge BEAUTIFUL chunk of salt.
Do you ever try make it by yourself?
You can warm it in the microwave to super saturate the salt solution further and make bigger crystals
My dad is diabetic, can I use splenda?
Does it have to be string, sorry for askin, but can it be a skewer, as a skewer is easier to hold while eating?
Yes you can use a skewer, but it will be harder to have it suspended in the jar without touching the bottom. Also dont forget to coat the skewer with the solution. Here is a little tip, after dipping the skewer in the solution coat the skewer with granulated sugar, and put it in the jar. The granulated sugar will act as seed crystals and will speed up the process a bit
jstyledipset Thanks, you could probably do the same with suspending it in the jar, except just taping it to the pencil
No
you can also use a skewer but i would recommend getting it wet and dipping it in sugar, so the crystals have something to begin growing on. check out my channel for my way of making rock candy for more info
Crystallization of sugar :)
Ok, well that is wonderful, but no one is really gonna wait a week to make candy!
This video that about crystalisation processes as geologic gives important informations
Well if u use 3 cups of sugar its such a waste
Try putting in 2 strings instead of 1
Is it because it's so concentrated in crystallises or is it chemical reactions?
Saturated*
holy moly that is a lot of sugar!
I have no clue of what happens. But it does tastes nice.
a week goes fast for ya then..
ikbeneenpop1 Maybe he's done it before...
isnt this the crystallisation method normally used to separate a soluble and insolube solid o.o
insoluble*
I like licked the screen it looks so good I'm doing it on Saturday or even today who knows
It looks really cool
Nucleation, my friends. Nucleation.
but can i use something other than a string?
would it work with brown sugar..
3 CUPS of Sugar !!!!!!!
saturated solution cools down the temperature and become crystal
I KNOW! why not, whats wrong with the crystals forming on the string
This is very cool!
Too lazy to make it? You can call Saul!
mustard gas
Isnt that a complete waste of sugar
cool
but i only do it for home work
he shud have 1000000 Subs
I knew id see breaking bad comments
is this edible because it looks disgusting
Why is it called rock CANDY then??
114 willow grove elmore nj
It works because of science. Duhhh!
it rots?
