McDonald’s recently said that it has better engineered a straw that will allow its customers to better enjoy the shamrock shake. McDonald’s sought the help of two engineering companies, JACE and NK Labs, in order to achieve its goal.

What brought about this new change? McDonald’s is currently coming out with new flavors of the shake, like chocolate for example, and wants its customers to be able to experience the full flavor of the shakes. Yet to some a straw is just a straw. Most would like to know how has McDonald’s managed to engineer a straw that will better enhance drinking pleasures?

The fast food giant says, that the new straw design has the ability to deliver chocolate and mint in equal flavor ratio. That’s something a typical straw isn’t capable of. Even the principal engineer on the job, Seth Newburg, commented that “It was a puzzling assignment but one with an ambitious goal.”

The result of all the engineers hard work and effort paid off with the result of STRAW or Suction Tube for Reverse Axial Withdrawal. It is believed that STRAW has the capability to demonstrate wondrous dynamics when it comes to fluids. It design was in part thanks to the aid of Fibonacci’s sequence which in turn was developed thanks to the mathematical genius, Leonardo Fibonacci.

Let it be known that the hardworking engineers at JACE and NK Labs put a lot of hard work into the production of STRAW. It took months to produce the right results. Even though this entire ordeal would prove a bit flamboyant especially when talents of such engineers could be put to far better uses, it shows that McDonald’s would choose only the best when it comes to enhancing the flavor experience of its consumers.

The consumer can be on the lookout for this invention that is set to hit at least 80 McCafe sites as the Shamrock shake makes it appearance in the next few weeks for the upcoming St. Patrick’s Day. However, due to the STRAW’s unique design, there might not be enough for everyone. In fact, McDonald’s says it only ordered around 2,000 or so because larger orders wouldn’t arrive in time for the holiday.

Yet when it comes to enjoying your shamrock shake with your newly designed straw don’t think you’re limited to just one flavor. The straw can be used to enjoy the flavors of the Shamrock Chocolate Chip Frappe, Shamrock Mocha, and Shamrock Hot Chocolate.

McDonald’s hoped that this new campaign will hold out a bit better as opposed to previous ones. For instance, making the happy meal healthier didn’t go over as well as the company had hoped. The campaign allowed for the replacement of toys in the happy meal box for fitness trackers. There was also the switch from French fries to apples which McDonald’s learned caused problems between parent and children.

However, there are high hopes for the STRAW. “From a physics perspective, it’s actually quite difficult to deliver a proportional amount of both chocolate and mint flavors with each sip,” Newburg said, yet somehow McDonald’s has managed to do so.
