Last time I heard, adding water to whiskey ruined it, so I don`t see the point in the whole thing anyway.
It`s fairly obvious that bouyancy is the key here just as its fairly obvious that this is a nice little party trick, not a suggestion of a practical method of swapping the glasses. There`s really no need for everyone to tell us that they too understand that whiskey is less dense than water and that they have a more efficient method of pouring drinks. Try adding something new...
The setup doesn`t just rely on bouyancy. The most important thing going on here is the surface tension round the edge where the liquids pass- and that`s far cleverer.
yet ANOTHER retard, not shocking...
But zullol, you`re way off on your explanation. It has nothing to do with concentration...if it did, the whiskey and water would reach an equilibrium point where there were equal parts whiskey to equal parts water at any point in the system. This is differential density. Whiskey floats on water because it is less dense. It`s as simple as that.
That`s a REPOST, its already been posted further up!
Jesus has a website?
STFU, anyone can post on here - does it really matter if it is a repost?
