Notjer Posted June 11, 2007 Share Posted June 11, 2007 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. Link to comment Share on other sites More sharing options...
Sayonara Posted June 11, 2007 Share Posted June 11, 2007 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)?

Darkblade48 Posted June 12, 2007 Share Posted June 12, 2007 I thought it was just because you are providing more sites of nucleation for the carbon dioxide? Link to comment Share on other sites More sharing options...
