On February 23  McDonald's announced the release of a limited edition straw that was designed for their new Chocolate Shamrock Shake. Only 2,000 of the innovative shake-slurpin' devices were made. The Suction Tube for Reverse Axial Withdrawal (aka STRAW) was created so that patrons could get both layers of the new beverage (chocolate and mint) in one even sip. No mixing required. It also was supposed to make milkshake drinking a much smoother experience, boasting three well-placed holes on the bottom of it's "J" design.  For this event, McDonald's worked with a pair of aerospace engineering companies -- the same guys, in fact, who helped spearhead Google's Project Ara modular phone.  So consider the STRAW the iPhone of straws. The STRAW uses a J-shape with five passageways. Many people want to know if it is necessary. According to Geeks Who Eat "Our verdict: It is a lot of fun and while being superfluous, it is still pretty super! " Want to try it for yourself?
