McDonald’s USA has added to their already mouth-watering array of gourmet, a milkshake for which you need a straw, specially designed by engineers, to suck it out! McDonald’s new Chocolate Shamrock Shake is a dual-layered chocolate shake below a layer of regular Shamrock Shake. The delivery of its chocolatey goodness in the ideal 50/50 ratio was a problem that compelled McDonalds to hire professional engineers to resolve it.
The engineers have created a product called STRAW — Suction Tube for Reverse Axial Withdrawal. While it looks like a regular straw with a pair of holes at the curvy bottom; the two companies hired to work on the straw, Jace and NK Labs, will tell you that it was anything, but simple.
Seth Newburg, principal engineer and managing partner at NK Labs, said in a statement, “From a physics perspective, it’s actually quite difficult to deliver a proportional amount of both chocolate and mint flavors with each sip. But that’s exactly what we did. It’s a marvel of fluid dynamics.”
A Jony Ive-channeling McDonald’s presenter calls the STRAW “spectacularly unnecessary.” It would seem like something straight out of an April Fool’s classics, but McDonald’s claims of actually producing 2000 of these straws and releasing them in their distribution centers, tell another story. The STRAW will be given with the purchase of a Chocolate Shamrock Shake. Currently, it is only available in selected restaurants in the U.S.
