Slide 2:
Water molecules are strongly attracted to one another and will collect around a bubble of carbon dioxide that is found in the soda, forming a sort of coating. The Reaction
Slide 3:
For more CO2 bubbles to form, or for existing ones to grow bigger, they must break the surface tension of the water molecules. While breaking the water molecules’ surface tension contributes to the reaction, the experiment really requires the use of another property found in Mentos.
Slide 4:
The second property is the wealth of tiny, irregular pits and crevices that can be found all over a Mentos candy at a microscopic level, which are nucleation sites, or locations that are ripe for carbon dioxide bubbles to form.
Drop a Mentos candy into the soda, and a large number of bubbles will form all over the candy at the nucleation sites. As the candy sinks, it passes through more soda and creates more bubbles. Collectively, these bubbles create foam and the pressure necessary to cause an eruption.
Slide 5:
The theory with Mentos is that the gum arabic in the candy breaks the surface tension of these molecules, making the carbon dioxide bubbles form faster
