Just in time for carnival, we would like to introduce you to a cool experiment where you can make colorful rock candy yourself. The finished rock candy sticks are also super suitable for a children’s birthday party and the little ones can of course also participate in the production.

Make rock candy: A cool experiment that requires some patience
Candy sugar is easy to make at home, tastes great, and is a fun recipe to make with kids. Even better, it’s also a science experiment because you can watch the sugar crystals grow. It’s also a great opportunity to get creative in the kitchen, because the color and flavor combinations you can create are endless.
This is one of the easiest candies to make, although it does require patience. All you need is sugar and water, and a few basic materials that you probably already have around the house. Most of the steps involve making the sugar syrup and preparing the sticks and jars. While you should start to see changes within the first few hours, it can take three to seven days for the rock candy to form.
Remember that the exact amount of sugar syrup will depend on the size of the jars and the number of rock candy sticks you want. For example, the quantities in the recipe are for four 200-milliliter jars and 4 candy sugar sticks. You can easily double or triple the recipe to make more rock candy at once.
Make your own rock candy sticks: here’s how!
Growing colored sugar crystals is an interesting project that doesn’t require any special skills. You will be able to see the result only after a few days, but the children will certainly be eagerly waiting for it. Now we will explain how to make the candy sticks yourself.
First, gather the following ingredients:
- Water and granulated sugar in a ratio of 1:3, in this case 400 ml of water and 1.2 kg of granulated sugar.
- 2 to 3 drops of food coloring, optional but recommended for colored rock candy
- 1/2 to 1 teaspoon of flavor extract or oil
and these materials:
- 4 glasses of 200 ml each
- 4 wooden skewers
First, rinse four 200 ml jars thoroughly with hot water.
You will need a wooden skewer for each jar, hanging about an inch above the bottom of the jar. Furthermore, you will also need clothespins balanced over the top of the jar to hold the skewer in place.
Prepare wooden skewers
Moisten each wooden skewer with water and roll it in granulated sugar. This base layer will give the sugar crystals something to cling to as they begin to form. Set the skewers aside to dry while you prepare the sugar syrup.
Prepare the sugar syrup
Add 400 milliliters of water to a medium saucepan and bring to a boil. Gradually add sugar, stirring after each addition. You will notice that it takes longer for the sugar to dissolve with each cup added. Continue stirring and boiling the syrup until all the sugar has dissolved completely. Remove the pot from the heat.
If you are using coloring or flavoring, add 2 to 3 drops of food coloring and stir in to achieve an even color. If using an extract, add 1 teaspoon of the extract; for flavoring oils, add only 1/2 teaspoon. Be careful not to stand directly over the pot, as the fragrance can be very strong when it rises in the steam.
Now let the sugar syrup cool for 20 to 30 minutes.
Rinse the prepared jars briefly with hot water and then distribute the syrup into the jars, not filling them full.
Insert a sugared shish kebab skewer into each jar until it hangs about an inch above the bottom and secure it to the rim of the jar with clothespins.
Grow sugar crystals
Carefully place the jars in a cool place away from light where they can stand undisturbed. Cover the jar opening loosely with plastic wrap or a kitchen towel.
Within 2 to 4 hours, the first sugar crystals should begin to form. If you see no change after 24 hours, try boiling the sugar syrup again and dissolve another cup of sugar in it. Then pour it back into the jar and stick the skewer in again.
Allow as many sugar crystals to grow until the candy sticks reach the desired size. Do not allow the candy to grow too large or it may grow out the sides of the jar.
Note that a top layer of crystals will also form. This is fine. Once the candy reaches the desired size, break up the top crystal layer with a fork before removing the candy.
Place the candy sticks in an empty jar (keep the clothespins for balance) and let them dry for 1 to 2 hours.
Enjoy the colorful candy with the kids or wrap the sticks in plastic wrap and save them for later.
