| This is kinda gross but it's a cool and nifty little trick. My roommate showed me this a few months ago during a game of beer pong. When you pour beer, soda or any carbonated beverage into a cup you get foam or fizz. Sometimes barely at all, but this applies to the cases where you get a lot. If you take your finger and run it along the side of your nose or along your hairline, anywhere 'oily' and then take said finger and dip it lightly into the foam, swirling it around once or twice, the foam begins to dissipate immediately and very rapidly. Anyone know why? |

| the chamicals in the nose gold you've been mining break down the particles in your drink. Rather that than seeing the freshly poured drink burn the skin off your finger eh |

| Same reason you put a little oil into the water you use to cook pasta, it keeps it from boiling over. I guess the oil breaks the surface tension of the bubbles causing them to pop. |

negative.
the oil is for when you take out the pasta from the pot, to prevent it from sticking. nothing else. :thepirate |

| Nothing to do with the oil... it's all about the finger. Putting a finger into the fizz creates an imbalance in the surface tension of the bubbles thus they break and release the trapped CO2. You get the same result using pretty much any rough surfaced object. |

ah but the oil does make a difference. Just stirring your finger through it doesnt cause the bubbles to dissipate nearly as quickly as when you have the oil on it. Try it out, it's surprising. |

Isn't oil a component of soap? Which breaks the surface of water (miniscus?)? Which would let the gas escape directly rather than bubble up and form... bubbles?
I think that makes sence. |

| The first bar I worked at, they told me about this trick, and said if beer was foaming too much, I should slide my finger around the edge of the inside. I never did it because I am a massive germaphobe, but yea, apparently it works. I was told it had something to do with the salt content in your skin. :conf: |
