If you got any sour gummy worms for Halloween, they’re probably coated with sweet-sour powder made from citric acid and sugar crystals. Using the same science used to make rock candy, you can use sour gummy worms to crystallize sugar syrup and make an”icy worm pond.” It’s even more fun to add sugar cubes to your pond! After a few days, you can chip your worms out of the “ice” to see how they taste. I created this experiment for Imperial Sugar and Dixie Crystals. Check it out on their website (click here) for directions and to learn more about the science behind the fun!
If you don’t have sour worms, try coating other (non-chocolate) candy with sugar by dipping it in water, rolling it in sugar and letting it dry before you add it to your pond. It would be fun to do this experiment with Swedish fish, or lifesavers!
