As the trend of DIY coffee production becomes increasingly lazy, the Coffee Mix Straw seems about right. Although still only a concept, the adult pixie stick provides the latest in ill-advised coffee technology.
Just break off the end, pour the mixture into your awaiting water, stir, and something resembling coffee will magically appear. The stick then quickly becomes an oversized bendy straw.
Or, you can always take a cue from its pixie stick influence and pour the powder right down your gullet.
