For anyone who keeps a growing collection of mason jars at home, one simple discovery is taking the internet by storm. A TikTok user recently revealed a quick, practical trick that makes organizing jars easier than ever — and it starts with something already in the pantry: a peanut butter lid.
The Trick Everyone’s Talking About
TikToker Samantha Johnston (@samanthajohnston93) shared a short clip that’s now catching attention from home organization fans everywhere. Her video shows a standard peanut butter jar lid fitting perfectly on a mason jar. It’s a detail most people never noticed, yet it solves the age-old struggle of finding the right lid for the right jar.

Many popular peanut butter brands use lids with threading that matches wide-mouth mason jars. That means instead of throwing those lids away, they can be repurposed to keep kitchen staples neatly sealed and fresh.
Johnston’s caption summed it up simply: “I put everything in Mason jars and peanut-butter lids fit perfectly.”
Why It Works
This small yet clever fix doesn’t require any special tools or effort:
1. Rinse the lid and let it dry completely.
2. Screw it onto a compatible mason jar.
3. Enjoy an airtight seal perfect for spices, snacks, nuts, or small hardware items.
Because the lid is plastic, it’s lightweight, easy to clean, and less likely to rust than metal tops — making it ideal for everyday use.
A Small Change With Big Benefits

Beyond convenience, this trick highlights a larger idea — reusing what’s already available. The United States disposes of millions of tons of plastic each year, much of which ends up in landfills or oceans. Reusing items like jar lids helps cut down on that waste while saving a few extra dollars on new storage products.
It’s also an approachable step toward low-waste living. Unlike major eco-friendly shifts, this one doesn’t need expensive gear or complicated systems. It’s as easy as paying attention to what can serve a second purpose before tossing it out.
This mindset can extend beyond the kitchen: old containers, clothes, and household items can often be reused, repurposed, or even traded through recycling programs that give store credit or cash rewards.
The Internet’s Reaction
Viewers couldn’t get enough of Johnston’s discovery. Comments poured in from amazed users:
“Now these are the life hacks I need.”
“What?! Why did I not ever notice this?”
“Okay seriously, did not know that! Thank you for sharing.”
The simplicity of the idea made it instantly relatable — a satisfying “aha” moment for anyone who’s ever lost track of matching jar lids.
Little tricks like this prove that sustainability doesn’t have to be complicated. Sometimes, it’s about seeing potential in everyday items. Reusing a lid might not change the world, but it’s a small, conscious shift that adds up when more people take part.
By turning something as ordinary as a peanut butter lid into a useful tool, this one-minute hack brings both practicality and purpose to daily living — one mason jar at a time.
