McDonald’s Custom Made Milkshake Straw – Get Yours Quick

Remember the McDonald’s Shamrock Shake? Well it is coming back and McDonald’s wants to promote it by reinventing the straw for maximum shake drinkability.

“It was a puzzling assignment but one with an ambitious goal,” said Seth Newburg, principal engineer and managing partner at NK Labs. “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.”

McDonald’s is giving away 2,000 of these odd straws in the coming weeks. You can check out their site for details.
