Boil water, add lots of sugar, and put in a jar. Tie a string to a skewer and place over the jar with the string hanging into the water. Wait.

You will need

* 15cm piece of string
* A pencil
* A paper clip (or large plastic bead)
* 1 cup of water
* 2 cups of sugar
* A glass jar

What to do

1. Tie the 15 cm piece of string to the middle of the pencil.
2. Tie the paper clip (or bead) onto the end of the string.
3. Put the pencil across the top of a jar so that the string hangs down the middle of the jar. If it hangs down too far, roll the string around the pencil until the string is not touching the sides or bottom of the jar. The string will act as a seed for the crystal. Any type of jar will do, but canning jars, pint size are especially nice, they will endure the hot temperatures. Tall skinny olive jars are also nice because they don't use up so much of the liquid.
4. Now that the string and pencil are ready remove them from the jar and put them aside
5. Get a helpful adult!
6. Pour the water into a pan and bring it to boil.
7. Pour about 1/4 cup of sugar into the boiling water, stirring until it dissolves.
8. Keep adding more and more sugar, each time stirring it until it dissolves, until no more will dissolve. This will take time and patience and it will take longer for the sugar to dissolve each time.Be sure you don't give up too soon.
9. Have your friendly ADULT carefully pour the hot sugar solution into the jars to the top. Then submerge the paper clip and string into the sugar solution. Be sure the string hangs down in the middle of the jar.
10. Allow the jar to cool and put it someplace where it will not be disturbed.


Now just wait. The sugar crystals will grow for the next few weeks. When you mixed the water and sugar you made a SUPER SATURATED SOLUTION. This means that the water could only hold the sugar if both were very hot. As the water cools the sugar "comes out" of the solution back into sugar crystals on your string. The string and paper clip act as a "seed" that they start to grow on. With some luck and patience you will have a tasty scientific treat! Enjoy!

These ingredients
1 cup water
2 cups of granulated sugar
A few drops of your favorite candy flavoring such as peppermint, cherry or lemon, more drops = stronger flavor (optional)
A few drops of food coloring, more drops = darker color (optional)


Directions

Tie one end of the piece of string around the middle of the stick or pencil. Cut the string, if necessary, so that it is a little shorter than your jar.
Moisten the string with a little water and roll it in the sugar. Put the paper clip on the end of the string to help it hang straight down. Lay the stick over the top of the glass jar so that the string hangs down inside the jar. The end of the string should not touch the bottom of the jar.
Cook the candy mixture. (Here's where you need an adult to help!)
Put the cup of water into the sauce pan and heat until it boils.
Add 2 cups of sugar to the boiling water while stirring. Keep stirring until the sugar dissolves. (If you have a candy thermometer the temperature of the sugar water should reach 240 degrees Fahrenheit.)
Remove pan from heat. If you want to add flavoring or color, stir it in now.
Pour the hot mixture into the jar.
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 to 10 days (or more). There are two things that will make the largest crystals:
Making a thick sugar water mixture (Be sure you put in the whole 2 cups of sugar, or even a little more.)
Letting them grow for more days
When you're ready to eat the rock candy, take the candy-covered string out of the jar. Break the pieces apart and enjoy. Store left-over candy in a covered container. (Some adults like to flavor tea or coffee by putting a piece of rock candy in the cup. Maybe you shouldn't use purple coloring if you want to share your candy with them!)
Remember to brush your teeth!

Dissolve a lot of sugar in hot water, in a bowl. Hang some thin strings in it. As it cools, the sugar will deposit out onto the strings.
