Why does nose grease disolve beer foam?

Question

I first found it digustinng then found it helpful lol please explain this occurence.

Answer 1

you can do the same thing with a pat of butter (touch it instead of your nose). The foam is caused by the tensile surface of the beer. even the tiniest amount of any kind of oil will change the tensil surface properties, and therefore NO foam. :-)

Answer 2

So the person trying it will look silly sticking their nose in their beer. But seriously I never heard that, I guess it works like the foam in soda disolves when you put your finger in it.

Answer 3

If you feel silly touching your nose you can do the same thing by touching your forehead. This way you can be less discrete. But to answer your question, it is because you are adding salt to the foam.

Answer 4

the foam is air and protein chains, when you introduce an oil into the protein chains they break up, it's like sticking the end of your finger into the foam after pouring coke, it dissolves away alot faster from the oils on your fingertip. However coke is acidic on its own, while beer isn't, so foam takes longer to go down then coke. :)

Answer 5

It's not the oil from the skin of the nose or the salt , It's the hair inside the nose that absorbs the foam.

Answer 6

I heard it was the salt on your skin.

Answer 7

the heat from your body!
