Just in time for St. Patrick’s Day, McDonald’s has brought back its mint flavored “Shamrock Shake.” YUM! And this year, they’ve also introduced four new Shamrock flavors, like their Chocolate Shamrock Shake. But the biggest news from McDonald’s is that they have released a super high tech straw, which was designed by aerospace and robotic engineers, to give you the perfect milkshake experience. Whaaaaaat? We’re so on board.

The STRAW, which is an acronym for Suction Tube for Reverse Axial Withdrawal, was designed specifically with the dual-flavored Chocolate Shamrock Shake in mind. The straw sucks from both the bottom and the top at the same time, giving you the perfect 50/50 ratio of mint and chocolate.

Here’s the STRAW:

Oooh cool. And look how heavenly these shakes look.

We can’t wait to try them!

McDonald’s hired two engineering firms, JACE and NK Labs to get the job done. Of the milkshake challenge, principal engineer of NK Labs Seth Newburg said in a McDonald’s press release, “It was a puzzling assignment but one with an ambitious goal. From a physics perspective, it’s actually quite difficult to deliver a proportional amount of both chocolate and mint flavors with each sip.”

Yeah, we don’t even know where we’d start.

Newburg continues, “But that’s exactly what we did. It’s a marvel of fluid dynamics. Thanks Fibonacci sequence.” Not sure what that is, but we’re loving it. Get it? “I’m loving it”?

Some of the other flavors sound amazing as well. The new options include Shamrock Chocolate Chip Frappé, Shamrock Mocha, and Shamrock Hot Chocolate. Drooling. Why can’t these shakes be around all year long?

Only a couple of dozen stores will be passing out a total of 2,000 of these super cool STRAWs on a first come, first served basis. Check to see if your state is participating here!
