Rainbow rock candy

 Science experiment:

Rainbow rock candy

We had such wonderful success the last time we made rock candy that we created a whole rainbow.  

You'll need:

• a bamboo skewer


• granulated sugar


• tablespoon


• a glass bead or other small object


• small jar


• 1/2 cup of very hot water


• a pencil

1. Before you start dip bamboo skewer in water and then in sugar (let dry completely.  This will give the sugar a base to start on)


2. Microwave 1 cup of water till it boils.


3. Pour water into large glass.


4. Stir in sugar a little at a time till the water will no longer dissolve it.  (a few sugar crystals will linger in the water).  It seemed to hold about 2 1/4 cups sugar for the 1 cup of water.


5. Add food coloring.


6. Place bamboo sticks in sugar solution.  (I tied mind to a pencil to hold it up)


7. Wait for 1-2 weeks.


8. A sugar layer will start to harden on the top of the sugar water.  Carefully break this away so that the water can evaporate.

 

Don't forget to keep the crystals that build up on the sides and bottom.  They are yummy too!
