This Is Why There's Always More Air Than Chips In Chip Packets

We all know how annoying it is when you open a packet of air... oh, we mean, chips. 

Turns out there's actually a good reason for it, though!

It's actually called 'slack fill', which is needed for when packs are crammed into tight spaces, put on delivery trucks or delivered in anyway so that there's an air cushion stopping the crisps from crushing.

It's also not just oxygen that comes out of the packets once they're opened. They're filled with nitrogen, according to Mental Floss, because oxygen makes the potato snacks go soggy.

That's why pringles can have so many in their packs - because the packaging is a lot sturdier!
