To create an explosion using Sprite, drop Mentos mints into the soda. The candies and the soda have a chemical reaction that forces the soda to release all of its dissolved carbon dioxide at once, which causes an eruption.Continue Reading
Any carbonated soda or diet soda will work for this experiment, including Sprite. Using normal soda makes the eruption sticky. Mint-flavored Mentos candies work best. The smooth waxy coating of fruit-flavored Mentos does not produce an eruption.
Drop the Mentos candies into to the bottle of soda. You may use as many as you want. Back away quickly to avoid being covered in soda.
Mentos mints dropped in soda results in a strong eruption. The eruption is a result of a chemical reaction between the aspartame and potassium benzoate with the gum arabic and gelatin in the Mentos mints. Because the mint Mentos are uncolored and unglazed, the surface provides more nuclation places for the carbon dioxide dissolved in the soda to escape suddenly as a gas. The chemicals in soda like potassium benzoate, which is a preservative, cause the eruption to be more violent than Mentos in carbonated water.
