When you pour a glass of coke, or other fizzy drink, into a clean, dry glass, you often get a lot of fizzing and froth that needs to settle down before you can top the glass up properly, unless I remember to angle the glass exactly right to get the pour spot on.
Yet when I go to refill that same glass a bit later, where the glass has now got just the remnants left, you don't get the same fizzing and frothiness and can pour the glass to the top in one go.
Why?
It can't be anything to do with the "fizz" having left the drink whilst its still in the bottle becuase if I use a new glass again, it will still fizz and froth up.
If you pour coke/champagne/beer/whatever into a cold glass, it hardly froths at all. I always assumed that the cold bubbles hitting a warm glass caused them to swell/explode.Yet when I go to refill that same glass a bit later, where the glass has now got just the remnants left, you don't get the same fizzing and frothiness and can pour the glass to the top in one go.

Should my router be down stairs so that they all rise up to my bedrooms, or should it be upstairs so they all fall down to the lower rooms?
Depends what you're downloading. Is it mostly 1s or mostly 0s?Should my router be down stairs so that they all rise up to my bedrooms, or should it be upstairs so they all fall down to the lower rooms?

I’m not sure temperature is the main factor - if you chill a glass it’ll have some condensation on the sides which calms the bubbles down.One way to guarantee a s
t pint is moisture in the glass.simoid said:

English dishwater ales, maybe. On the Continent, it's common practice to fire ice cold water into a glass immediately before filling with beer.
Sorry I’m meaning (fizzy) lager. Damp glass, the head will disappear fairly quick. Dry glass, plenty of bubbles form and keep the head. Continental lager maybe naturally more gassy?

or a fuel line....
But it's not as simple as that is it. It depends on fuel flow rate, the position of the fuel pickup, how quickly the old fuel and the new fuel mix in the tank, and what ratio of new fuel to old fuel you are going to define as "using the new fuel".

I know it would depend on a number of factors, but how far - roughly - would you get from the filling station before the car started to use the 'new' fuel you've just put in the tank?
You have put diesel in your petrol car haven’t you?Master Bean said:
I have a cold. Is there a limit to the amount of snot your body can produce? I'm getting through tissues like there's no tomorrow.
Yes, it's using your body's liquid reserves but you'll replenish them with drinks and food so, in theory it won't stop but the reason it is doing it is to expel the germs that make you feel so ill. Once it's done that and killed the rest it'll stop. I'm in mid-man-flu and despite drinking loads I am hardly weeing as I am blowing my nose constantly and so losing fluids that way.
