In this case substance A being:

Juice of half a lime

and substance B being:

a Can of Coke

creating substance C:

Kinda lime-tasting coke. It's rather lovely really. Go on, indulge your curiosity.

I wonder how much money Coke spent coming up with that tagline. Will it be as effective for me, having spent zero dollars, and instead just borrowing it from them? I know I tried Vanilla Coke as soon as the opportunity presented itself, not that it was a result of advertising really; I think it's the first non-diet alternative coke flavour that's been released in Australia, so I wasn't really a hard sell there.

Next up: How wide is wide. How broad is iziah?

AAAAhhhhhhhhhh coke craving. I need a can of coke. Or a six-pack would be better. All the shops are shut. I think I'll go to the pub and get a pint of coke. This is all your fault.
