Step 1: What you need:
One almost empty bottle of syrup. Note: When i say almost empty I mean not washed out, there's always left over syrup in the bottle and usually that's enough!
Milk. Any kind will do, we happened to have Fat Free in the house so that's what i used. Whole milk usually tastes the best.
A Measuring cup Don't fret now, there is no measuring involved, that would make this too complex. I just used this for pouring the milk into the bottle (see step 3). A Funnel I suppose would be just as good if not better.
A Glass (for the end result)
