Diet Coke And Mentos Why Does It Happen

Diet coke and mentos why does it happen. Usually the trick is done using diet soda especially diet coke or another cola however the main reason for this is because diet drinks are less sticky easier to clean up than other sodas. Bubbles and soda will quickly shoot out of the bottle in a high fountain. Coffey and company discovered that the ingredients in the mentos and diet coke and more importantly the structure of the mentos allow carbon dioxide bubbles to form extremely rapidly.
Why does it work better with diet sodas. We are looking the different factors affecting the way that soda explodes. However most of the carbonation is released from the soda as it is being drunk so the pressure is lower and carbon dioxide is less likely to nucleate.
When all of this gas is released it forces the liquid up and out of the bottle in a giant whooshing geyser of sticky soda. Now you test the hypothesis. Theories abound as to why this happens.
As to why diet sodas like diet coke produce such a bigger reaction it s because aspartame lowers the surface tension of the liquid much more than sugar or corn syrup will. As this is the reaction based on carbon dioxide gas. When you drop mentos into the soda then all the carbon dioxide bubbles comes out of the soda all at once.
The candies catalyze the release of gas from the beverage which creates an eruption that pushes most of the liquid up and out of the bottle. There is an urban legend that eating mentos while drinking soda could cause a person s stomach to burst. Lee marek and marek s kid scientists were the first to publicly demonstrate the experiment on the late show with david letterman in 1999.
Do a little bit of research about the ingredients of mentos and soda. 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. A diet coke and mentos eruption is a reaction between the carbonated beverage diet coke and mentos mints that causes the beverage to spray out of its container.
