Among the many beverage blends that are available commercially, Coca-Cola and milk is not one that you will see at your local supermarket anytime soon. However, it is the perfect mix for one awesome viral YouTube video, in which an experiment shows what happens.
After one hour passes, the liquid inside the bottle looks clear, as brown residue sinks to the bottom of the container, according to the Irish Examiner. It looks like an "invisible soda," but how do the laws of physics explain the phenomenon?
An "aha moment" is provided thanks to a particular science gadgets and experiment site. That is where the blog Steve Spangler Science is found.
The separation of the two liquids happens when milk and phosphoric acid react. After the molecules of phosphoric acid attach to the milk's molecules, the density rises.
The milk-phosphoric acid mixture then separates from the other liquid in the bottle. Those liquids have a lower density than the milk and phosphoric acid molecules, so they float to the top of the bottle, according to Huffington Post.
Soft drink producers add phosphoric acid to their products to make their flavor crisper. The acid also reduces the growth of nasty bacteria and molds in the sugary drinks, which would not likely improve your soda-drinking experience.
Interestingly, nearly all of the acid from sodas originates from phosphoric acid, rather than the carbonic acid. However, the acid concentration of soda is still lower than drinks such as orange juice.
In January the exponent's video was first posted. However, this week the video became viral again, and has been viewed over four million times!
