People have only just realised why Ritz Crackers have ridges.
If you've never had a Ritz Cracker before, firstly, where have you been? And secondly, you need to buy some right now, because you're missing out.
Ritz Crackers are salty - but not too salty - crispy, and according to TikTok users, have a hidden function.
The delicious savoury snack has seven perforations and a finely scalloped edge, which most of us may assume is for aesthetics, but apparently, they actually serve a purpose.
A man on TikTok, known as ( @kenshawn.caraballo ) posted about their intended use and as a result, left dozens of people in a complete state of shock and surprise.

"I was today years old when I realised why crackers have ridges on them," he says at the start of the short clip.
He then demonstrates how to make full use of the ridges.
In the clip, he can be seen rolling the jagged edge of the cracker over a piece of cheese to effectively cut it.
This way you have a perfect sized piece of cheese to fit the cracker - and you save on washing up.
Since being posted, the video has racked up more than 15,500 likes and hundreds of comments from people who were "mind blown" by the revelation.
One person wrote: "Never knew this."
A second person commented: "Well now I know this. Thank you."
A third simply said they were: “Mind blown".
But someone else claimed this wasn't news to them, saying: "I’ve always done this…"
This isn't the only fact that people have learned from TikTok recently.
One man went viral on the social media platform after he shared an "extra use" for door springs.
They demonstrated the hack in a video on their account, which was captioned: "From doorstopper to doorkeeper."
They said if you need your door to stay open, and you have one of these springs on the wall behind it, simply bend the stopper down, open the door fully over the top, then release.
The stopper at the end will stop the door from closing.
Take a look for yourself, here.
