Steven Universe’s “Crystal Gem” Candy Recipe / Experiment

Week Two of Camp Warner Bros. is here and this week we have a SWEET science experiment that the kids will love. We will be making Crystal Gem candy to celebrate the release of Steven Universe: The Movie.

Enter to win a copy of the movie at the bottom of this post! 

After so many harrowing adventures, Steven and the Gems are ready to celebrate how far they’ve come with a movie musical! Little do they know they’re about to face their worst enemy yet. 

Steven Universe: The Movie is now available to own on Digital, Blu-ray & DVD.

Save the Earth and bring peace to your galaxy with Steven Universe’s “Crystal Gem” Candy recipe. This recipe/experiment requires adult supervision because you’ll be handling hot liquids. I also want to preface this experiment with a disclaimer that we have tried to grow rock candy before with no success. This is a touch on to get just right. Even making the recipe below we only had two successful crystal growths out of four. 

The Science Behind The Fun:

As time passes (and the solution cools), the water will slowly evaporate from the solution. As the water evaporates, the solution will become more saturated with sugar. The sugar molecules will collect on the string, and the candy crystals will grow molecule by molecule!

Extra Science Fun:

Try making two jars of candy. In the first jar – seed your “Crystal Gem” Candy by rolling your string in water and sugar. In the second jar do not seed your string with sugar before growing. Determine if using seed sugar crystals changes the growth rate of your “Crystal Gem” Candy!

We made our Crystal Gem Candy a little different because I had the materials to put them on sticks and also flavor them. We used flavor extracts in each of them. Aside from the sticks and extract, everything else is the same. 

Win Steven Universe: The Movie!
