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

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.

This was so helpful! Thank you!!!

Amazing! Thanks for the explanation

so cool and easy thank you soooo much!!

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

great video!! thanks a lot

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

Great job! Thanks for sharing your work!

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

Thx needed this for my project

Good way of explanation to reason of crystallisation of sucrose🤗

Nice experiment I am going to try Thank you

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

Mmmm... delicious chemistry!

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

Thank you

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

mmm can't wait to try this!
