As it sinks, the Mentos produces more bubbles, which react with carbon dioxide in the soda, rewarding you with a Diet Coke geyser. Speed also matters, and the faster the Mentos sinks, the larger the eruption. Mentos are dense candies, which aids the sinking process — a factor the study explored by comparing reactions made with whole Mentos
Mentos, the makers of Mentos Chewy Mints, explains on its website that soda and other fizzy drinks contain a certain amount of carbon dioxide (CO2) that is dissolved in water in the form of tiny bubbles or carbonation.

The temperature of the soda also factors into geyser size. Gases are less soluble in liquids with a higher temperature, so the warmer your soda is, the bigger your Mentos-induced geyser will
A Mentos dropped into a bottle of soda acts as a surfactant, meaning it reduces the surface tension of the soda. Water molecules are polar and attracted to each other. Anything that breaks them apart allows for bubbles of carbon dioxide gas to form in the solution.
The crushed Mentos candy should sink slower than a whole Mentos candy. In this materials science project, you will see if using crushed Mentos candies instead of whole Mentos candies, which should sink faster in the soda, will change the height of the eruption. You will crush Mentos candies and then use them to make Diet Coke geysers.
