A popular science experiment for children and adults is growing crystals at home. This process can show how crystals form in nature. These beautiful crystals can be grown using simple household products, such as baking soda, water and jars. AND the crystals will form starting within the first day

Step 1: What You Will Need

1/4 cup Baking Soda
2 cups Distilled Water (less impurities than tap water)
2 8-Ounce Jars
1 ft of Yarn
2 Paper Clips
Food Color (optional)

Step 2: Begin by Making a Super Saturated Baking Soda Solution

Place 2 cups of distilled water into a sauce pan over very low heat
Begin adding baking soda, a little at a time
Stirring mixture continuously
Continue adding baking soda until water is over saturated (when you see the baking soda settle to the bottom of the pan, approximately 1/4 cup)
Remove from heat and cool completely

Step 3: Prepare Jars and Yarn

Clean 2 small 8 ounce jars with warm soapy water and rinse
I used Mason jars, but you can use any small jar
Set jars approximately 6 inches apart on a plate
Cut a piece of yarn approximately 12 inches long
Tie a paperclip to each end of the yarn to serve as weights to hold the yarn down in the liquid
Pull or push the two jars together until the yarn forms a 'smiley' shape in-between them

To speed up the crystal growth process, you can soak the string in the saturated solution before stringing it between the jars

Step 4: Pour Solution Into Jars

Fill both jars with the saturated baking soda water solution
Make sure the 'smiley' part of the yarn hangs below the liquid
Place your experiment in a place where it won't be disturbed during the crystal growing process. Even the slightest movement may cause the experiment to fail
Leave the jars for 2 to 3 days to allow the crystals to form
