Viewers responded in a variety of ways, mostly fascinated by what happened.

"Incredible," one wrote.

"This looks disgusting," said another.

The producer of the video offered a scientific explanation for the chemical reaction:

It is a reaction of the Phosphoric Acid contained in the coca cola to the milk. Phosphoric Acid molecules attach to the milk giving them more density and separate out while the remaining liquid that makes up the milk and cocoa cola now being lighter floats on top. The solid matter is basically milk that has been curdled by the addition of the more acidic soda.

Both items are acidic but coca-cola more so. In general, coca-cola has a pH of anywhere from 2.5-4.5 because of the Phosphoric Acid content where milk has a normal pH around 6.7 (almost neutral, milk that is in the base range is usually mastitic).
