This old puzzle is often tackled using mathematical formulas, or the much easier and sudden "Aha!" it would appear that the milk would have more Kahlua than the Kahlua had milk, because, in the second pouring, the mixture is no longer pure. However, since there is once again a full litre of each liquid, whatever amount of Kahlua that was removed had to be replaced with the same amount of milk. The key to this puzzle is realizing that we are left with two one-litre containers of liquid. A couple of you figured this out with Legos, and it was an excellent manoeuvre.
