Finally, a "better mousetrap" for martini drinkers — the Metrokane Flip Top Cocktail Shaker
(from the folks who brought you the Rabbit Wine Opener) offers a neater, cooler, easier way to mix cocktails.  The rocker-cap flips open to strain, closed to shake (just make sure you've got the top fully seated and closed before shaking). And the stainless-steel shaker is insulated, so slow-sippers keep their second cocktail cool, and the shaker cup doesn't sweat.  Watch it in action here. Buy it for $30 with free shipping from Amazon.com.
