Do other sweets explode in Diet Coke?

No, only Mentos candies have the unique combination of ingredients and texture that creates the explosive reaction when dropped into Diet Coke. The specific combination of gum arabic, gelatin, and sugar in Mentos candies, along with the carbonation in Diet Coke, creates the ideal conditions for the formation and rapid release of carbon dioxide bubbles, resulting in the explosive effect. Other sweets, such as chocolate, hard candies, or gummy bears, do not possess the same combination of ingredients and texture to produce the same explosive reaction.
