For the purpose of dissolving a powdered mix into a mostly full beverage cup, which common kitchen utensil would be the fastest/most effective?
I often find myself using a fork thinking that the tines provide more turbulence or mixing action than a spoon. I have no proof this is the case it is just something I have done. I also find stirring straws work well for me since I can move them rapidly without making the mix swirl so much that it overflows the cup. In my experience I tend to find that spoons are the worst because I can't move them very fast before the liquid begins to get near the edge of the cup. I haven't used knives very often so I don't have an opinion on them.
I do not have a background in fluid dynamics and no real evidence of any of this, nor have I done any studies/comparisons other than my perceptions which may or may not be correct. Anyone have other information or tests they have done or observations to add about which utensil would be the best?
