Rock Candy

Hi guys, today I wanted to share with you how we made rock candy during our cave unit study. 

Ingredients

3 cups of sugar

1 cup of water

A pot

Jar or a cup with small opening

Clothes pins

Stick or skewer

Sugar

Adult supervision is required. Mix together sugar and water stir well and set it on the stove top. Keep mixing until the sugar has completely dissolved and the solution starts to bubble. You can add food coloring and flavor to your liquid at this point. Set aside for 10 minutes to cool. While your solution is cooling take your skewer and dip it in water. Roll it in some sugar and leave it to dry. This will be your seed crystals. Once the solution has cooled pour it into the jar. Suspend your stick in the solution using the clothes pin. It takes about 7 days to grow your rock candy.

After seven days you can remove your rock candy. Slowly chip away the sugar crystals around the sides. Remove the stick and suspend it over another empty glass cup or jar. Allow the excess sugar to drip away. Enjoy your candy.
