Making Rock Candy
Hi and welcome to my blog today ill be talking to you about making rock candy.
Aim- To make rock candy.
ROCK CANDY EXPERIMENT
Materials (per rock candy color)
- 2-3 cups of sugar
- 1 cup of water
- Skewers
- A jar or glass
- A large saucepan
- Clothespins
Optional additions:
- Food coloring
- Candy flavoring
Method
- Combine equal parts of sugar and water in a saucepan and heat until all of the sugar is dissolved.
- Then, slowly add more sugar and mix, slowly adding more sugar and mixing until the sugar will no longer dissolve in the water.
- The water should start to look a little cloudy. That is when you know that no more sugar is dissolving and the perfect sugar-saturation has been reached.
- The short version is that you are creating a saturated sugar solution, or a solution in which no more sugar can dissolve at a particular temperature.
- The amount of sugar verses water used should be roughly 3:1. You can easily double & triple the recipe as long as you mantain a 3:1 ratio.
- Add candy flavoring if desired, and then continue to heat the water until it comes to a simmer.
- Remove the sugar-water from the heat and allow it to cool.
Preparing the Candy Sticks
- Cut the skewers to a desirable size for the jar(s) that you are using. Then, dip the sticks in water and roll them in sugar.
- Set the sugar-coated sticks aside and allow them to dry.
Prepping the Jars
- Once your sugar-water is cool enough pour it into jars, using one jar for each colour of rock candy that you wish to make.
- Once the sticks are dry carefully place them into the jar(s).
- You want to make sure that the sugar-coated sticks are completely dry before placing them in the jars.
- The rock candy needs the sugar on the sticks to grow, and if the sugar isn't dry it will dissolve in the water.
- It is also important to make sure that the sticks are not touching the bottom or sides of the jar.
The Experiment
It is now time to sit back and observe the jars!
When I tried to make the rock candy I did not work as it did not from any crystals. Thank you for looking at my blog.
Ah no, it didn't work? That's a shame, do you have any idea why it might not have worked? Science sometimes doesn't work and that's ok, as long as we try to find the reason for why it didn't work. Very well written method though.

ReplyDeleteThis is a great blog, and I agree with Mr Heath - you have written out your method very well. It's a shame it didn't work out for you this time, but if you can work out what you did wrong maybe you could try again. Another idea might be to compare recipes because maybe there is a problem with your recipe. Maybe next time you could also include some pictures of your ingredients and with you working on the method. Good luck for next time!
