You won't believe what this new McDonald's straw can do

(McDonald’s)

You may have been drinking milkshakes the wrong way your entire life.

McDonald’s USA shook up the blended beverage world yesterday with a limited-edition straw professional engineered to flood your mouth with the perfect balance of flavour.

The fast food giant’s new seasonal Chocolate Shamrock Shake has dual layers of chocolate under green-dyed mint to celebrate St. Patrick’s Day. But the problem persisted on how to get exactly 50% chocolate and 50% mint in each sip. JACE and NK Labs rose to the challenge and invented a j-shaped Suction Tube for Reverse Axial Withdrawal (the STRAW).

“From a physics perspective, it’s actually quite difficult to deliver a proportion amount of both chocolate and mint flavours with each sip,” Seth Newburg, managing partner at NK Labs, told MarketWired. “But that’s exactly what we did. It’s a marvel of fluid dynamics.”

If you want to snag one of these ultimate shake-drinking experience tools for a hung-over binge-eating episode, you better plan ahead. Only 2,000 were produced in time for Shamrock season and the STRAW will only be for sale in select locations with the purchase of a Chocolate Shamrock Shake.

“We’re always listening to what our customers want and reinventing our menu in response,” Darci Forrest, senior director of menu innovation at McDonald’s has said.

How about adding some bourbon to that shake next year?
