Crystal Gem Candy | Week 2 of Camp Warner Bros.

Steven Universe: The Movie

The girls and I had so much fun doing this Crystal Gem Activity together. I handled the stovetop part of the activity while the girls did everything else. The only mason jars I had on hand were the super-sized ones, so to make enough Crystal Gem solution I quadrupled the recipe. 

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

Crystal Gem Candy Tips

At first, it may not seem like there will be enough for your jar, however, once you combine the sugar and water together and let those two cook for a minute. The solution more than doubles in size and can fill a medium-sized mason jar easily.

While the directions call for “food coloring” which we assumed meant the liquid drops, we only had gel food coloring on hand. We had no issues with our gel food coloring, minus the fact that our purple became very dark and hard to see through. I would suggest if you are planning to make a purple jar and are using gel food coloring, make sure you go slow with the colors. 

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!

CAUTION: This activity requires adult supervision at all times. Please use caution when pouring hot liquid.

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!

Crystal Gem Candy

It’s crazy how fast these Crystal Gem Candies grow! In just a few short hours we began to see the crystals forming on the string and around the jar. The pictures below show what the gems look like after growing for 24 hours in a dark cabinet. After day 3 we had enough on our strings to enjoy while watching Steven Universe: The Movie.
