Initial heating of the phenol and formaldehyde (in the presence of an acid or base to get the reaction going) produced a shellac-like liquid good for coating surfaces like a varnish.
开始加热，酚和甲醛(需有酸或碱促使其反应进行)便产生了像紫胶样的液体，能像清漆一样涂于物体表面。

Theories abound as to why this happens, with some bloggers speculating that it is an acid-basereaction because Coke is acidic.
一些blogger们深思后得出了解释这一现象的原因的理论——这是种酸碱反应，因为可乐是酸性的。

Measurements of the pH of the Coke before and after the experiments showed that its acidity did not change, ruling out the idea that a simple acid-basereaction drives the fountains.
