Halfway Mark

Here is a trick to making your gallon of vitamin D milk stretch a little bit further. Drink the first half of the gallon as usual. When it gets to the halfway mark, add water to it, nearly to the top, but not quite. Your kids will never know - no fooling!
While it may seem an obvious trick to some, I am sure there are many out there who would not dare try it, without having heard of it being tested, (on kids), first. It only works with whole milk, not 2% or 1%, try it.
