Cola foam and sweat


Recommended Posts

It is a hot day in Denmark. Some people enjoys it, and some people just wants to cast a curse on days like those. I had been outside in the beautiful nature and now I am enjoing a fresh cold pepsi max cola. The warm day also means that I have sweat a lot. My skin has a taste of salt of course, however I wonder why the foam in my cola disappears faster than normal when I touch it with my salty fingers.


Could someone explain what happens and why when I touch the foam? I have a basis knowledge of the structur of foam.

Are you sure it is the salt?


Have you compared the effects of touching the foam with sweaty/salty fingers, against the effects of touching the foam with fingers that only have water on them (or nothing at all)?
