Write down what happened when you dropped the Mentos in the coke. The speed at which the Mentos falls through the soda can affect how large the eruption is, and this can be tested by comparing whole with crushed Mentos, the latter of which are less dense. The result is a massive eruption of foam, shooting stories high into the air. Preparation. Why do Mentos mints foam when you drop them into soda pop. Like you did before, place your full cartridge on top of the flat index card, then line up where the opening of the bottle is with the opening of your cartridge. The exception was citric acid, which did increase fountain height too, but which required slightly more than usually used in drinks. The gas form of carbon dioxide bonds with the water molecules present in the cola. The basic science of the Coke and Mentos reaction is fairly straightforward. It can be a change in the shape or appearance of an object, like crumpling a piece of paper, or cutting, bending, or dissolving something. Physical changes include transitions from one state to another, such as from solid to liquid or liquid to gas. Mentos are a type of candy that contains sugar, glucose syrup, and a variety of flavors. When mint or fruit Mentos are dropped into a fresh bottle of Diet Coke, a jet of Coke whooshes out of the bottle's mouth and can reach a height of 10 metres.

On the wax paper, carefully use a knife to crush and cut four Mentos candies into many small pieces. 
What is Mentos and Coke Reaction in Human Body? Make sure to check out our Sugar-sweetened drinks tend to be more viscous, which likely slows bubble formation, leading to smaller fountains than for their diet counterparts. Instead it is a physical reaction. This is a messy experiment. Take the straw out of the soda and put a pipe cleaner in. Investigating further, it was found that when the substances were dissolved in water, the bubbles produced were smaller. 4. Thankfully, theres already a well-known escape hatch located at your mouth. The rough, dimply surfaces of Mentos encourage bubble growth because they efficiently disrupt the polar attractions between water molecules, creating bubble growth sites. 
What is a physical reaction example? 2023 Scientific American, a Division of Springer Nature America, Inc. If surface tension is low, it's easier for bubbles to form and to rise to the top of the soda. The change of matter which occurs without changing its chemical composition is called a physical change.
