Life saver. I failed at this twice because I under cooked the sugar. I was waiting 2 weeks so crystals to grow. This ensures my kid can get her science experiment done on time. Thank you.
No problem I am glad to hear and it makes me happy to know these videos get good use especially when it comes to school projects. Thanks for dropping a comment and letting me know! :)
I just had to leave a review after making this last night before I went to bed....I used a .50 walmart cup, bamboo stick and clothes pin/clip. I woke up and came to the kitchen to check it out and OMG, it's the biggest rock candy i've ever seen! AMAzing! thank you!!! This works!!!
If you rotate this string or stick on which you want to crystalize - back and forth, it will make crystals faster and bigger. Reason is that during crystal process, "depleted"water sitting near the crystal, and tend to dissolve it back. By rotating, you moving your crystals through new saturated area, while depleted water (under-saturated) tends to go away.
This worked great for my daughter's last minute science project she came in second place we did four different colors the school loved it! Thanks so much for this video😁
I needed to find a better way to make sugar clusters for a geode cake. This is exactly what I was looking for and will be trying it out tonight. And thank you for the explanation as well! So much easier to do when you understand why something is happening!
@@TrollFaceTheMan I'm sure there was some user error but it didn't work as well as I had hoped. I definitely got some crystals but I still had a lot of slush.
Can't wait until next weekend when my granddaughter comes over she will love ❤️ it plus I really like how you explained the science behind the growth she is ten and loves science.
Perfect! I’m trying to learn some new candies to make for Easter this year. I’m going to try this. Thank you for teaching me something new! I make cooking videos too! It’s a pleasure to learn from other talented creators like you! I hope we can learn more from each other! Have a great weekend!
Impressive video. I know a lot of homeschooling moms who will find this useful. I was laughing a bit though, wasn't expecting the nerd's version of how to make rock candy but it's very cool you took time to do all the work.
I'm so doing it right now. Thank you very much for this video, I understood most of it (English isn't my mother tongue) and I'm certainly going to rewatch it to understand everything properly. The only problem is that I don't think I have a candy thermometer :"/ Guess I'll have to ask the mighty Amazon. Thanks for putting this on Instructables!
The crystal is really big especially for 4 hours I whould put it in a bhcket it would get huge or in a swimming pool that hasn't been use and sell them for 1 thousand dollars
Hello thank you very much for the great video I tried it yesterday but I only used 3 and a half cups of sugar ( I was afraid I would't control the freezing process if I use alot of sugar ) after 4 hours I got nothing on my stick, I was like yeah it probably didnt work.. but today when I woke up, a beautiful rock candy was formed I'm so proud , I'll do it again using different colours
KarascioM Indeed you can so long as you heat it to the same temp, you should be able to grow new ones without a problem. Though you might have to add more water initially to get the sugar to redissolve.
I love how this guy includes kids and talks about safety a lot I am a kid and god no I do not use safety but the idea of the safer procedure in my head helps me a lot I may have been in a couple of phosphorus explosions but I'm fine
I LOVE LOVE LOVE this demo! I have read the slower it cools the bigger the crystals will be?! Can you do a video and show this process, would you use a heating pad? Or oven? I'm really interested in what other ways this can be done. Can you cool it fast in the fridge and get better results? There's not one video I haven't seen on rock candy and I keep coming back to yours! Thanks so much!!!! I would love to see more videos on this and other ways to grow this!!!! Your awesome!!!
Cooling it slower will give you larger crystals because it slowly builds off the existing crystals instead of branching off into many tiny crystals like in this video. I have a sugar solution that had been in the fridge for half a year and it has large blocky crystals.
@@TrollFaceTheMan I was just trying to troll you troll face The man, I take it back after seeing more of your content and who you are as a human being. Sorry. How’s your hearing and did that tumor turn out to be benign ? I hope your doing good man
@@ojifididitsimpson, oh okay. Yes luckily the tumor was benign. And I am permanently deaf on that side but luckily I was able to get a cochlear implant as part of an experimental surgery where they simultaneously removed the tumor and installed the implant. The cochlear implant allows me to hear through direct nerve stimulation. It is limited but still nice to have. Helped with the tinnitus from the deafness a lot which is a relief.
@@TrollFaceTheMan hell yeah man, I hope things start looking up Genuinely hope the best for you. You seem like a good guy. Sorry for being a weirdo. It’s the internet.
At least your spoon has a covering, (not bare metal), so I'm sure helped with heat? Might I suggest you or anyone dealing with sugar syrup in any candy making? USE WOOD OR BAMBOO SPOONS 😱 Great video. Thanks!💜
I like the addition of the vanilla flavoring and was just wondering if you could use lemon juice? I am a lemon fanatic and would love to make lemon candy.
Yes you can but as a fore warning adding too much can stop the Sugar from crystallizing. My personal theory for this is a because the acid in the lemon juice causes the Sucrose the sugar is made up of to instead 'Invert' and break down into Fructose and Glucose which doesn't like to crystallize. Especially when mixed with one another.
What can you use the leftover sugar for? Can you make more out of it? Repeat the entire process, with the same sugar, reheating etc?? How many crystals can you make from that recipe??
This is why im 2yrs into the comments trying to figure out what fucking temp to set the syurp to, candy making is so freaking precise most of the comments say they burnt or made Carmel. What bs
Okay, QUESTION TIME! Can you take remaining syrup and re-use for another batch? Also, if you had a much taller glass (heat proof) jar, could you make a much longer string of it?
Herøy man. I must say that i really have enjoyed the quality of videoes you been putting up lately. They are easy, clean and simple. My only complaint would be the quantity of videos. But i am sure you are busy with school or real life stuff Anyway, keep up the good work
I wrote this above to another user, but I think it'll work nice here too. "I apologize about the delay between releases, my goal has been to make really High Quality videos from here on out. But these Crystal vids have a lot that goes into them, especially with the time lapse and all... It took me 2 days to get everything edited and another on top of that for recording so it is a major time consumer, and unfortunately I have to work and make money still which takes priority... "
TrollFaceTheMan Also it is like -10 out so I haven't been able to do any outdoor projects XD And indoor ones have so much more that goes in them, as you have to set up lights, make sure Animals/People are not making noise, thoroughly clean up any mess you make... Try not to burn your house down... Ect.
That is just what i thought. Real life stuff absorbing. I understand that when youtube isn't your job, you can't invest as much time in to it. Just keep the good work man. Quality over quantity :)
Only to be attempted by someone responsible Me: set the kitchen on fire making brownies, set the kitchen on fire melting butter, broke the oven thinking you had to bake buttercream, put a battery on my toung amd electrocuted myself cause i was bored, has forgotten to take socks off until im in the shower every time, has put milk in the pantry amd cereal in the fridge, has put a fork in the bin and tin in the sink way to many times for my own good, very acident prone (been told by a docter i am😅) Also me: yup im safe and responsible
What would happen if I put the syrup solution on a baking sheet instead? Low long should it take to cool to become solid so I can peel it (carefully ) into a large rectangular sheet of sugar?
+5Smarties It's possible that Crystals might of formed on the side of the pot you were making the solution in. Those crystals then could of fallen into said solution and triggered it to start Crystallizing prematurely. That would be my guess.
Hello This is nice I just need to know how many sugar with one cup water and at what temperature was the sugar Reddy and will Thier be a way to take the sugar crystals off the string ? I was thinking of making smaller sugar treats ?
Becuase of forcing the solution into super saturation by driving off more water then what is needed to keep the sugar dissolved. As it cools that additionally cuases the sugar to want to crystallize even more/faster. Look into "Hot Ice" it is sodium acetate. Very similar concept.
Method did not work so well for me... I had a lot of trouble with the string, it kept floating to the surface, I finally had to wrap the string around a skewer but I think by that time, the sugar around it fell into my syrup... I'm over 12h-waiting period and barely have any build-up sugar :(
The way you measured the water and sugar was absolutely fabulous.
Well thank you :)
