Kool-aid Rock Candy

FUN SCIENCE:  Grow your own rock candy using Kool-aid!  ( SO COOL!!)
We first tried making our own rock candy a few years ago.
Today, we revisited this experiment but with a fun twist!

Do you think you can make rock candy from Kool-aid?  

That was the question I posed to my girls this morning.  After careful consideration both girls made their predictions, and then we jumped right in.  Rosie and Jewel were so excited!  


Step 1

Preparing the Skewers
  • Begin by soaking the bamboo skewers in a container of water.  Leave them to soak for at least one hour.
  • Remove the skewers from the water and then coat the bottom half in sugar.
  • Set the skewers aside and allow them to fully dry.

Step 2:

Preparing the Sugar Solution
  • Begin by pouring 4 cups of water into a large pot, and then place it over medium heat.
  • As the water heats slowly add white sugar one cup at a time and stir until dissolved.
  • Continue to add more sugar and stir until you can not get any more sugar to dissolve in the water.   (Just to give you an idea I used almost 10 cups)
  • Once this occurs bring the mixture to a boil and then allow the mixture to boil slowly for 10 minutes.
  • Remove the pot from heat and allow the sugar mixture to cool for 10-15 minutes.
  • While the water is cooling you can prepare your glass jars.  Pour one packet of Kool-aid into each jar, using one jar for each color/flavor of rock candy that you wish to make.  
  • Then, pour the sugar water into the jars, and then stir each one until the Kool-aid is dissolved into the water.
Now, take a break, and wait for the glasses of sugar water to cool to room temperature.  This part is very important!!  Once the water is cool it is time to submerge the bamboo sticks into the jars.
Note:  If you place the skewers into the jars too soon the heat from the water will dissolve the sugar on the stick, and the experiment will not work.

Also be sure that the sticks are NOT touching the bottoms or sides of the jars.  This is very important!

Now, we wait!  It will take roughly two weeks for your rock candy to fully form.  My kids loved checking on the jars each day and couldn't wait for the candy to be ready to eat!  

Here is what our jars looked like after five days

And after two weeks
Amazing, right?  My kids thought so, and after two weeks of waiting and observing they could not wait to dive in and taste this yummy treat that they made themselves!!  So cool!!

The Science Behind the Fun:

This activity is a great lesson in Science.  Be sure to discuss the Science behind the rock candy experiment and explain to little ones what is going on.  Rosie and Jewel were really fascinated with the Science.  Here are some helpful links for explaining just what is happening:


STICKY SAND: Mold it, build it, & CONTAIN IT! This sand acts wet, but it isn't! It sticks together well, but it does not stick to skin. My kids love this stuff, and I love the less-messy alternative to traditional play sand!
