Making our own crystal rock candy

Making rock candy




Instructions


Things You'll Need

1 cup water

2-3 cups sugars

paper and binder clips

food coloring

1 quart jars or glass

cotton strings

ice cream sticks

Food Coloring

Ice Cream Sticks

1 Quart Jars Or Glass

Pencils

Paper And Binder Clips

Cotton Strings




1-Sterilize the glass jar and paper clip by boiling both in water for a few minutes.


2-Tie a short piece of kitchen string to the middle of a pencil or Popsicle stick.

Attach the paper clip to the end of string. (The clip will weigh the string down - this is important later.)


3-Moisten string lightly and roll in sugar (this helps the crystals form on the string).


4-Place the pencil or stick over top of a jar. Make sure clip is in the bottom of jar and the string hangs straight down into jar.


5-Heat 1 cup water to boil.

Dissolve 2-3 cups sugar in boiling water. Keep adding sugar until it stops dissolving.


6-Add a few drops food coloring if you like.


7-Pour sugar syrup into jar and leave for 1 week or until crystals form on the string.
