how do you make rock candy?

Answer 1

1 Glass jar or drinking glass
1 Piece of cotton string
1 Pencil or stick
1 Paper clip
1 Food coloring (optional)
1 c Water
2 c Sugar
Additional sugar
Tie a short piece of cotton string to the middle of the pencil or stick. Attach a paper clip to the end of the string for a weight.
Moisten the string very lightly, and roll in a bit of sugar (this will "attract" the sugar crystals from the syrup to the string). Place the pencil or stick over the top of the glass or jar with the string hanging down inside.

Heat the water to boiling, and dissolve the 2 cups of sugar into it. For the biggest crystals FAST, heat the sugar-water solution a SECOND time, and dissolve as much additional sugar as you can into it. Add a few drops of food coloring to the solution if you want colored candy.

Pour the solution into the prepared glass or jar and leave undisturbed for a couple of days. Depending on how much sugar you were able to dissolve into the water, you should start to see crystals growing in a few hours to a few days.

Answer 2

• 4 cups sugar
• 2 cups water
• a small saucepan
• a wooden spoon
• a candy thermometer
• a small, clean glass jar
• a measuring cup
• cotton string
• a weight to hang on the string (such as a screw or galvanized washer)
• waxed paper
• a pencil (to suspend the string in the jar)

1. Heat the water in the saucepan over medium-high heat until it comes to a boil.


2. Completely dissolve the sugar in the boiling water, stirring continuously with the wooden spoon until the solution grows clear and it reaches a rolling boil.


3. Remove the solution from the heat, and then carefully pour it into the jar. Cover the jar with a small piece of waxed paper.


4. Tie the weight to one end of the string, and then tie the other end to the middle of the pencil. The string should be about two-thirds as long as the jar is deep. Dip the string into the sugar solution, remove it, lay it on a piece of waxed paper, straighten it out, and let it dry for a few days.

• Why does the string need to be soaked and then dried?


5. Gently suspend the prepared string in the solution and let sit at room temperature, undisturbed, for several days. You can check each day to see how much your crystals have grown. It’s tempting, but don’t touch the jar until the experiment is finished—it usually takes about seven days.

• What makes the crystals grow?


6. At the end of the week, the crystals on your string should be clearly defined, with sharp right angles and smooth faces of various sizes. In the field of crystallography, these are called monoclinic crystals. Their shape is determined by the way the individual sugar molecules fit together, which is similar to the way the shape of a pile of oranges is determined by the shape of the individual oranges and the way they stack together.

What Do I Do? Did You Know?
Rock candy is one of the oldest and purest forms of candy. It was originally used by pharmacists to make medicines for many kinds of illnesses.

1. Heat the water in the saucepan over medium-high heat until it comes to a boil.


2. Completely dissolve the sugar in the boiling water, stirring continuously with the wooden spoon until the solution grows clear and it reaches a rolling boil.


3. Remove the solution from the heat, and then carefully pour it into the jar. Cover the jar with a small piece of waxed paper.


4. Tie the weight to one end of the string, and then tie the other end to the middle of the pencil. The string should be about two-thirds as long as the jar is deep.

Answer 4

Ingredients

1 cup water
2 cups sugar (or even a little bit more!)
Candy thermometer
Saucepan
Long- handled wooden spoon
1 Pint glass jar (canning jars work best)
1 Clean popsicle stick
1 Clean piece of string (or another popsicle stick if you wish to make rock candy on a stick instead of a string)
Optional:

Food coloring
Flavoring (i.e. Vanilla Extract, Mint, Root Beer)


Procedure

Run tap water over the string
Roll moistened string in sugar
Tie the sugar coated string around the popsicle stick and place in the jar (make sure that the string does NOT touch the bottom of the jar)
Bring the cup of water to a rolling boil
Stir in the 2 cups of sugar
Continue cooking the solution until the candy thermometer reads 240°F (165.3°C)
Remove solution from heat. (If you wish to add coloring or flavoring to your rock candy, add it to the solution now.)
Carefully pour solution into glass jar
Set jar in a place where it won't be disturbed
You will notice crystals forming within a few hours. Rock candy will be ready to eat between a day and a week from the time it was cooked. Simply remove the string from the jar and enjoy your rock candy!

Answer 5

This is what i use to do...full a glass with sugar water..
tie a string on to a pencil put pencil string in sugar water glass for a few day stir and add more sugar to water. repeat. slowly but sure you will get rock candy

Answer 6

This is an old and very simple recipe.

Usually found in Betty Crocker or Pillsbury 1950ish cookbooks,
or on the little bottles of flavoring you'll need to purchase for
flavor. The receipe usually is on the back.

Go to a candy supply for the flavorings.

good luck
