how to make rock candy?

Question

how do you make rock candy at home

Answer 1

Rock Candy Recipe

Ingredients
(rock candy graphic) 4 cups sugar
1 cup water
Food coloring
Clean glass jar
String, cut into 6-inch lengths
Pencil

Instructions
In a medium saucepan, heat 2 cups of the sugar and the water. Do not boil! Stir until the sugar is completely dissolved. Gradually add a few drops of the food coloring of your choice and the additional sugar, stirring continuously until all the sugar is dissolved.

Pour the solution into a clean glass jar and tie the pieces of string to the pencil and suspend them across the mouth of the jar so that the ends hang into the sugar water.

Crystals suitable to eat will form in an hour and continue for several days to a week. Pieces can be broken off and eaten after the first hour. (But, try to hold out for big crystals!)

Although you may see quick results in small measure, the larger rock candy crystals you're accustomed to seeing in the candy store will take some time to form.

Yield: 12 ounces

Answer 2

Here is the recipe for how to make your own rock candy!

For this activity, the first ingredient you will need is an adult to help you! You will be working with very hot liquids on the stove and you need to stay safe at all times.

NOTE: This recipe is designed to make a single string of rock candy. Experimental results have shown that multiplying the ingredients by a factor of 2 or more and then carrying out the experiment will not result in the formation of rock candy crystals. Thus, this particular experiment is not easily adapted to making large batches of rock candy. Work is ongoing to develop an experiment for use in the classroom that will yield larger batches of rock candy.



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 4

you will need....
measuring cup & spoon
large heavy metal sauce pan
long wooden spoon
clean glass jar (mayonaise etc..)
piece of clean ccotton string
popsicle stick,pencilor skewer
pot holders
paper clip
candy thermometer

1 cup water
2 cups granulated sugar
a few drops of candy flovoring
a few drops of food coloring

1. tie one end of the string onto the stick ,cut the string, if necessary, so that it is a little shorter than your jar.
2.Moisten the string with a little water and roll it in the sugar.Put the paperclip on the end of the string to help it hang straight down inside the jar. Lay the stick over the top of the glass jar The string shoukd not touch the bottom of the jar.
3.Cook the candy
a.put the cup of water into the pan and heat till it boils.
b. add 2 cups of sugar to the boiling water while stirring. keep stirring tilkl the sugar dissolves.( if you use the thermometer it should reach 240)
c.. remove pan from heat. If you want .now is the time to add the color and flovoring.
d. pour the mixture into the jar
4.
Let the sugar water sit for a few days where no one will bother it. The crystals will begin to form along the string in a few hours. Let them grow for 3- 10 days(or more)
There are two things that will ake the largest crystals.
a. Making a thick sugar water.Use all the sugar 2Cups
b. letting them grow for more days

Answer 5

• 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.

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.

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.

• Try adding food coloring or flavoring to your sugar syrup before making the rock candy.

Answer 6

This is good, easy recipe - you can experiment with different flavors - just invest in a good thermometer



ROCK CANDY

1 3/4 c. sugar
1/2 c. water
Food coloring as desired
1/4 tsp. flavoring oil
1/2 c. light corn syrup
Dash of salt
Confectioners' sugar

In a small saucepan combine sugar, water, corn syrup and salt; stir until sugar dissolves. Cover and bring to a rolling boil. Remove lid, place thermometer in pan and cook until 250 degrees. Add food coloring and continue to cook to 300 degrees. (Remove from heat at 285-290 degrees as temperature will continue rising to 300 degrees.) Let cool a few minutes. Add flavoring oil and cover 5 more minutes.
Pour into buttered 7 x 10 inch pan. Cut with shears into strips as soon as cool enough to handle. Cut into squares or diamond shapes. When cool, dust with confectioners' sugar to keep from sticking. Makes about 50 pieces.

Answer 7

i know you need two things at least glucose syrup and sugar. I have no idea how you combine them.
