Didn’t get a chance to participate in the Rock Candy activity this week?
Give it a try and enjoy some delicious rock candy!
- 4 glass jars
- Sugar (5-6 cups)
- Food Coloring
- Clothes Pins (4)
- Wooden Skewers (4)
**Parental Assistance is NECESSARY**
- Clip pins on the ends of each skewer. Place the skewers into jars and measure so that they are sitting 1-1 ½ inches from the bottom of the jar (also make sure the skewers are located in the middle and not leaning against the edges of the jar). Then remove the skewers and set aside.
- Using a medium sauce pan, boil water and add 1 cup of sugar, stir till it dissolves. Continue to add ½ cup of sugar and stir, until sugar can no longer dissolve.
- Remove pan from heat and let it cool for about 20 minutes. During cooling, dip skewers in the syrup mixture then coat them with sugar. Place in jars, tip facing upwards, to cool.
- Once the syrup mixture cools, remove skewers from jar and add 10-15 drops of food coloring to each jar. Next, pour in cooled syrup mixture and fill jar about ½ inch from the top of the jar. Stir mixture and food coloring to mix.
- Carefully add skewers, tip facing downward, into jars. Make sure the skewers do not touch the bottom of the jar or the edges.
- Let jars sit for 1 week! When ready, remove and let them dry for 1-2 hours. Now you’re ready to eat and enjoy!
The purpose of this experiment is to observe the crystallization process. If you would like to keep track, make a chart and draw the daily changes you see!
