You may find yourself super hungry during the break, which is probably a result of your boredom, but that is neither here nor there! If you are hungry, why not involve science!
Here is what you do:
How to Make Rock Candy
Step 1: Combine equal parks of sugar and water in a saucepan and heat until all of the sugar is dissolved.
Step 2: Slowly add more sugar in small amounts until it will no longer dissolve in the water (for each cup of water, 3 cups of sugar is needed)
Step 3: Get to the point where the water starts to look cloudy. That is the point when no more sugar is dissolving and the perfect sugar saturation has been reached.
Step 4: Add candy flavoring and continue to heat the water until it comes to a simmer.
Step 5: Remove the sugar-water from the heat and allow it to cool. While it is cooling you can prepare your skewer. Cut the skewers to a desirable size for the jars you are using. Dip the sticks in water and roll them in sugar.
Step 6: Allow the sugar coated sticks to dry. While those are drying you can prep your jars. Once your sugar-water is cool enough, pour it into jars and add food coloring if desired. Then, once the sticks are dry, place them in the jars.
Step 7: Make sure the sticks are not touching the bottom or the sides of the jar by using the clothespins
Step 8: WAIT for at least a week for them to grow.
Science behind it:
Why does the string need to be soaked and then dried?
The string will provide the surface on which the crystals will grow. As water evaporates from the string, small crystals of sugar will encrust the string. These tiny seed crystals provide starting points for larger crystals. Future growth will be concentrated around these points.
What makes the crystals grow?
Two different methods will contribute to the growth of the crystals on the string. You have created a supersaturatedsolution by first heating a saturated sugar solution (a solution in which no more sugar can dissolve at a particular temperature) and then allowing it to cool. A supersaturated solution is unstable—it contains moresolute (in this case, sugar) than can stay in a liquid form—so the sugar will come out of solution, forming what's called a precipitate. This method is called precipitation.
The other is evaporation—as time passes, the water will evaporate slowly from the solution. As the water evaporates, the solution becomes more saturated and sugar molecules will continue to come out of the solution and collect on the seed crystals on the string. The rock candy crystals grow molecule by molecule. Your finished rock candy will be made up of about a quadrillion (1,000,000,000,000,000) molecules attached to the string.
