Re: The glass is...

[pajout]

There is two glasses. The first contains 2 dcl of red wine, the second 2 dcl of white wine. You will sequentially move one spoon of wine from 1. gl to 2. gl, mix it, two spoons from 2. gl to 1. gl, mix it, and one spoon from 1. gl to 2. gl. Is more concentrated red wine in 1. gl or white wine in 2. gl. ? (No side effects, no jokes...)
Update: I prefer red wine...

I would say about the same.

But anyhow, I still don't like wine. So we could trown them away and get that 2l of Pepsi instead!
