Mentos And Soda Geyser

Chemistry Level 2

A mint-flavored mentos makes a geyser 5 meters high and a fruit-flavored mentos makes a geyser 2 meters high when the two candies are put into identical bottles of soda under identical experimental conditions. What is the most reasonable hypothesis to explain the difference?

Mint candies are more basic, increasing the acid-base reaction Mint candies are more acidic, increasing the acid-base reaction Fruit candies have a more rough coating, decreasing nucleation sites Fruit candies have a smoother coating, decreasing nucleation sites
