Rock Candy Recipe - Crystallization of Sugar - The Sci Guys: Science at Home 

Equipment/Ingredients needed: 0:42 Sugar Pot Tall glass Clip or clothespin wide enough to cover the top of the glass Wood skewers or popsicle sticks (Optional) Flavoring Directions: 1:11 The first step in our experiment is to make a sugar solution to put on the stove. Add one cup of water to your pot then three cups of sugar, mix them all together until they're thoroughly mixed. Next, take one of your skewers and dip it in some water and then roll it in sugar. Once it's coated set it aside until it's dry. While you wait for your sticks to dry place the pot that contains the solution onto the stove and turn the stove up to high. Continue to stir your solution as it warms up. Once your solution begins to boil stir it rapidly until all the sugar has been mixed into the solution. Once all your sugar is mixed in this is a great time to add any flavoring or coloring. Once you're done mixing in all your sugar colors and flavors remove it from the burner. The next step in our experiment is to take your boiling solution and pour it into the glass in which you're going to grow your crystals. Let the solution cool for 10 minutes and then place the sugar-coated stick into the middle of the glass and hold it in place with the clip. Leave your solution in a warm dry place to cool as it cools crystals will begin to grow on the stick. The process of growing these crystals can take a couple of days up to a couple of weeks. Check crystals daily and make sure that the crystals growing on the stick don't come in contact with any crystals growing on the sides or bottom of the glass. If you notice they're growing close together reposition the stick so it's further away from other crystals. Once your crystals are done growing use a knife to crack the top shell of your solution. Gently remove your crystals from the solution and hang them in a new glass using the clip to hold it in place to drip and dry. Once your crystals have finished dripping and drying you are done!

The way you guys present their material is soo informative and elegant, God bless

This was so helpful! Thank you!!!

Amazing! Thanks for the explanation

so cool and easy thank you soooo much!!

great video!! thanks a lot

Great job! Thanks for sharing your work!

Thx needed this for my project

The only thing i need to worry about during the crystalization process: *ANTS*

mmm can't wait to try this!

we are doing a science fair project and you guys saved us because we didn't have a question until we watched your video!!!!!!!!!!!!!!!!!!!!!!!!:):):):):)

We had fun making the rock candy but just a suggestion, the darker the color the more difficult it is to see the process of the rock candy forming.

Mmmm... delicious chemistry!

Nice experiment I am going to try Thank you

Good way of explanation to reason of crystallisation of sucrose🤗

Great video.

thanks for the video I was so excited to see the video

Thank you

Great video

Awesome 😎👏🏻🧠

now that I can hear what a great vid thanks guys

awesome!!!!!

Good candy. Yum

NICE CRYSTALLIZATION OF SUGAR ON ROCK CANDY RECIPE !!!

Thank you guys so much now i got something to so for my science fair❤❤❤😘😘😘😘😘😘😚😚

i love this plz make more videos of sci guys and have a good valintines i will leave more post

The rock music joke was cringy, but great information. Also, I like your accents. And candy.

thank you

did u add food color to the sugar solution prior to putting your sugar stick in ? thank you

Wow on 5.1k likes?! This is so underrated!! Also this really helped with my science fair project!!! 😁😊❤️

Nice video! 😃😃😃

When I was a kid in the 50’s you could buy the rock candy in a store, plus, my mom taught me how to make the rock candy.

may you do a video about why do cells divide and all about cell division? please from your fan

In this video or in your first experiment, how long did it take before you removed that crystals in the solution? Thank you.

me to :) thx for the idea

Hmm.... delicious candy😋

Wait hold up. We need goggles & thermal gloves to... boil water? This has to be a joke right?

THANK YOU FOR THE HELP NOW MY SCIENCE PROJECT WILL BE SUCCESSFUL!!

hi its my first time watching The Sci Guys me and my mom love you can you make a video on making a pancake challenge plz plz plz!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

How cool does it need to be? What’s the temperature it needs to be below?

Can you put them in the fridge or in just a random place?

Thanks

This is cool

Wow I like it ...🤗🤗🤗

Thank you so much and

Can the boiled sugar solution be reuse?

0:22 are you experienced?

How does citric acid affect the crystalization? Would it be like the food colorings you added in this video? Or something completely different? Sour candies are my favorite :D

I try it and it workwow

Hiiii can I ask? For our modules only. How would you know that the crystals are already forming? How do crystals form?

Is the final product a mechanical mixture or a solution now

Hi! Can You Make a video of how to make slime?

Finally a recipe that doesn't require any methylamine

i have a week to perform the sugar crystal experiment and complete my report. Because i have never done this before, i am not sure how long should i let it crystallize? I need the crystal to grow to a size where i can interpret, compare and discuss my results. I was thinking about 5 days max, although i will have to rush to finish my report.

A point that might have been worth saying is be careful poring the boiling solution in the glass as it may crack or break

Best rock candy

hai, I wanna ask if I use less sugar does the crystel formed faster or slower???

Question can you use the same sugar solution to make more

how much water , sugar did you use

yum

Can we grow them in plastic cups??

Hello Guys, how many days does it takes to crystalize the whole process , and do we again have to mix more sugar after we make some sticks out of it . Thx

Ty

hi! i find your videos very helpful especially for a student like me..just wanna ask if you have any simple experiment for Stoichiometry? thanks! :)

who misses sci guys ✋

i have a tricky one for y'all! i wanna make a solid that will dissolve in water however it needs to be of a softer texture so i can put a hook through it for fishing... What can i make other then gelatin? I wish i knew what fish bites were made out of! Thanks for your time! i hope yall see this and have a solution for me!

Do you think you could do this with monkfruit sweetner

I love you guys😏😎😏😎😏😎☺☺☺

Man i wish I had no sense of humour so that I can laugh at the joke

We need an idea for a mumps virus model what do you think or what ideas do you The Sci Guys have for us and I think your rock candy experiment was awesome and cool and yummy😀😀😀😀😀😎😎😎😎😎😎😎😎

Yes

would it still taste like candy without food coloring or flavoring

We are still waiting for the results ✨

How long should I wait for string to dry

Do we need to refrigerate it

Can you make a tutorial on a terrarium?

Suggest me a idea on nucleation..

How long does it take to fully dissolve the sugar? and How long do we need to fully dry the coated stick?

Nice…

Muchas grasis idea it will not melt

It's giving sheldon & amy 💛

Sssooo cccooolll guys!!!!😱😎😎😂😍😘 Love it!!😘😍❤💓💖

would loved if they ate them get that crunch

it looked delicious! i have to try it out

is this experiment reversible or irreversible?

If we don’t have tol glass how can we make it

I tried this experiment but my sisters said you are not allowed to eat it since thee has been lots of dust travelling in the air and could've gone inside it.

I new you were mad scientisting with out me .M.I.T , finally paid off .... I’m still a bum in Torrance/South Bay.?miss me husband Ken

ryan is so funny and trysa is so scarry

Can we wait 3 days?

I have a question, how many days does it take to grow this?

jesse we need to make candy meth

Coool

in india this are called mishri and u will always get it in hindu temples as parsad (although not in stick form and no added flavour)

Organic Chemistry I, *thank you 👩🏽‍🎓*

is there a problem statement or question if so what is it ?

does that mean that if i put it in the freezer it will grow faster(the abrupt dropping of the solution with the sea-crystal as shown in the video nearing the end )

Did this experiment in 95 as a 5th grader. I don’t remember using that much sugar. Everything else on point. But we tied a string to a pencil to hang on glass. I don’t recall dipping the string

How long does it take to make these approximately?

I’m going to take some “sugar crystals” now😉😉
