Gear: The B4RM4N is a smart cocktail shaker that pairs with your phone via Bluetooth, helping you master your cocktail skills. After telling you what ingredients to extract, the B4RM4N shaker acts as its own measuring device with LEDs that light up as you pour, telling you to stop when the lights reach the top. Do this for the all ingredients and then give it a shake. The shaker will tell you what kind of ice to toss in there, and it’ll let you know when to stop shaking; it has a built-in accelerometer. You can even save recipes and share them later. Get one here.
