McDonald's have invented a J-shaped straw to help customers absorb their milkshakes better.
The fast food chain introduced the curved piece, which has holes on each side to help with suction, to enable milkshake lovers to enjoy their thick textured beverage when the drink can become lumpy and difficult to suck up.
And with just 2,000 pieces made so far, not all of their customers have been able to get hold of the innovative piece of equipment, according to the Daily Mirror newspaper.
However, the straw is rumoured to be making its way to the UK as the inventors have reportedly made the piece with a Shamrock Shake in association with St. Patrick's Day next month.
Principal engineer and managing partner Seth Newburg, who helped make the piece, said: "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 flavours with each sip."
