McDonald’s is pulling out all the stops this year with their Chocolate Shamrock Shake.

The folks at the fast food chain have partnered with aerospace and robotics engineers to redesign the straw.

The Suction Tube for Reverse Axial Withdrawal, also known as the STRAW, is J-shaped to deliver the best flavor flow dynamics. McDonald’s was looking to have 50% chocolate and 50% mint in each sip.

“It was a puzzling assignment but one with an ambitious goal,” said Seth Newburg, of NK Labs, in a release. “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. Thanks Fibonacci sequence.”

The STRAW’s design only allowed for 2,000 to be produced in time for Shamrock season.

“We’re always listening to what our customers want and reinventing our menu in response,” said Darci Forrest, senior director of menu innovation at McDonald’s. “And though it might sound silly to some, putting our guests first sometimes means re-thinking even the humble straw. We reached out to some of the brightest engineers in the country and asked for their help to create the ultimate shake-drinking experience.”

The STRAW is available on a first come, first served basis, while supplies last, with the purchase of a Chocolate Shamrock Shake at participating restaurants:
