Composition of Soda and Mentos : Composition of Soda and Mentos Soda is mainly composed of sugar, water, flavorings, and preservatives : Soda is mainly composed of sugar, water, flavorings, and preservatives Mentos contains gelatin and gum arabic : Mentos contains gelatin and gum arabic Sodas are bubbly because it contains carbon dioxide gas, which stays in the bottle till it’s opened : Sodas are bubbly because it contains carbon dioxide gas, which stays in the bottle till it’s opened Water molecules in the soda are strongly attracted to each other due to strong intermolecular forces and hydrogen bonding. These molecules link together and surround each carbon dioxide bubble. : Water molecules in the soda are strongly attracted to each other due to strong intermolecular forces and hydrogen bonding. These molecules link together and surround each carbon dioxide bubble. Increasing the number of bubbles or expanding these bubbles requires a lot of energy to break the strong linkages that form around each bubble. : Increasing the number of bubbles or expanding these bubbles requires a lot of energy to break the strong linkages that form around each bubble. When Mentos is inserted into the soda, the gelatin and gum arabic in Mentos breaks the ‘water molecule linkage’. Therefore, less energy is needed to expand these bubbles and form new bubbles. : When Mentos is inserted into the soda, the gelatin and gum arabic in Mentos breaks the ‘water molecule linkage’. Therefore, less energy is needed to expand these bubbles and form new bubbles. Moreover, Mentos contains lots of tiny pits, called nucleation sites, all over the surface of each piece of candy. Carbon dioxide bubbles form in these pits. Therefore, when Mentos is inserted into the soda, the entire piece of Mentos is covered in bubbles. : Moreover, Mentos contains lots of tiny pits, called nucleation sites, all over the surface of each piece of candy. Carbon dioxide bubbles form in these pits. Therefore, when Mentos is inserted into the soda, the entire piece of Mentos is covered in bubbles. When all the CO₂ gas from the soda and the ones that form on the Mentos are released, it pushes all of the soda out of the bottle like an explosion. : When all the CO₂ gas from the soda and the ones that form on the Mentos are released, it pushes all of the soda out of the bottle like an explosion.
