... you know when you go to some cafeteria place at a shopping centre, or any fast food restaurant for that matter (or even at the cinema), and you get out those cardboard cups and fill it with a fizzy drink of your choice, how the hell does the drink not fizz everywhere? :confused:

Picture this: you're at home and you are pouring a glass of coke, and you have to stand there like a mug while you wait for all the fizz to go down before you can fill the rest of the glass. Why does that not happen when you're out?

Its so bizarre! :p :D :o
 
The wax in the cups.

There's some fancy physics relating to boiling liquids and bubble formation.

It's all rocket surgery to me.

Because they 'water' it down somewhat, go to macdonalds and try their coke then try one from a corner shop and you can tell the difference bigtime.

EDIT: AS Gilly said less CO2 is added to the drinks and that makes it less fizzy than say a bottle or can of fizzy drink.
 
Off topic i know but i find this scary.

If you pour coke into a cup made of marble it becomes flat with out a single bubble almost instantly. :D
When i say flat i mean really flat, flat like you left the lid off a bottle for a few days

what if the inside of this cup was lined with impenetrable wax? ;)
 
its to do with the pooring device thingy

in mcdonalds coke comes as a syrup stuff (same in pubs) and carbonated water is added when u watch it closely it goes syrup, fizzy water , syrup in short bursts so it has time for the fizz to go down

Or does chicken taste like bogies? Hell, everything tastes like chicken. ;)

Oh and those syrup-C02 machines are cool. Try playing with the mixture for hours of "fun"
