McDonalds fans are only just realising why the McFlurry spoon is hollow

YOU might have spent many an occasion perplexed at the old McFlurry's plastic spoons with a hole in the top.

But you might not know the real reason behind its design - to stir your ice cream.

McDonald's recently revealed it would be phasing out all plastic cutlery, including the iconic spoon, across England and Wales restaurants in a bid to be more eco-friendly.

But many are only just realising now why the plastic spoon was designed with a hole and hook.

And it's because the spoon is attached to the McFlurry machine and used to mix up your dessert.

One fast food fan said: "I thought it was a straw - I always tried to drink out of it."

Another shockingly admitted: "I work for Maccies and somehow just found this out."

While a third added: "Bro, when I first had a McFlurry when I was like 10 I thought it was a straw."

It's not the first time food fans been left reeling after discovering a secret behind a product's design.

KitKat fans were left stunned after finding out what its wafer centre was made out of - other Kitkats.

Fans of the two or four-finger chocolate bar were left in shock at the revelation.

One said: "No way a KitKat is inside of a KitKat I never would have thought."

Another added: "That's why it's so sweet!"

It comes after McDonald's said it would be scrapping plastic cutlery to reduce its carbon footprint.
