Our in-home scientists made their own unique colas. They were each given small cups of soda water colored brown. They had their own choice as to how much sugar, vanilla, cinnamon, lime juice to add. After each addition, they had to taste-test and decide if they needed to add more of an ingredient. Then they recorded how much of each ingredient they added. Each cola was unique; one had a cream-soda flavor (James'), one had a cinnamony hint to it (Katie's). They all seemed to enjoy having the ability to make their own cola!
