Apparently it's just a "design concept", but this got me thinking:

With different sizes of straws, you could prepare "one-shots" of anything: Gatorade, Coffee+whitener, loose tea, instant breakfast powder, or whatever else you mix in with your pint of hot/cold water on the trail.
Not necessarily lighter, but possibly not more than a few grams heavier and there's a convenience factor in this idea.
