See Steve Spangler for a much more thorough explanation of this very cool experiment. General Chemistry Online!. HYPOTHESIS: I think that the number of Mentos will affect the height of the explosion because there are more physical reactions happening. Put the open end of your tube of Mentos on the card and place it directly over the opening of the soda bottle. • Also, none of the ingredients in Mentos are basic: sugar, glucose syrup, hydrogenated coconut oil, gelatin, dextrin, natural flavor, corn starch, gum arabic. 2.
