You remember that frantic fidget spinner craze of 2017? It was everywhere. Gas stations, high-end boutiques, and definitely every single middle school classroom in the country. While the metal and plastic versions eventually ended up in junk drawers, the physics behind them stayed pretty cool. Honestly, you don’t need to spend twenty bucks on a bearing-heavy piece of plastic when you can just use what's sitting in your printer tray.
Learning how to make a paper hand spinner isn't just a rainy-day craft for kids; it’s a legitimate lesson in torque and friction. If you do it right, a paper version can spin for a surprisingly long time. Most people mess this up because they try to cut a shape out of cardboard and stick a toothpick through it. That’s amateur hour. We’re looking at the interlocking origami method. No glue. No mess. Just physics.
The Secret to a Long Spin is Mass Distribution
Most DIY tutorials fail because they don't account for weight. Paper is light. If your spinner is too light, air resistance kills the momentum in seconds. When you’re figuring out how to make a paper hand spinner, you have to think about the "moment of inertia."
Basically, you want the weight on the outside.
I’ve seen people try to tape pennies to the ends of paper blades. It works, but it’s ugly. The better way is using multiple sheets of heavy construction paper or cardstock. If you’re using standard 20lb printer paper, you’ll need to double up the folds. It gives the edges a bit of "heft" so that once you get it moving, it wants to stay moving.
What You'll Actually Need
Don't overcomplicate this. You need two squares of paper. That’s the foundation. About 6 inches by 6 inches is the sweet spot. Too big and it’ll hit your knuckles. Too small and you can’t get enough leverage to flick it. You also need a toothpick or a plastic ink tube from a dead pen, and maybe two small buttons or circles of cardboard to act as "caps" for your fingers to grip.

Step-by-Step: The Interlocking Fold Method
Forget the scissors for a second. We’re folding.
Take your first square and fold it in half. Then fold it in half again so you have a long, thin rectangle. Do the exact same thing with the second piece. You should have two identical strips. Now, this is where most people get tripped up. You need to fold the ends of these strips into triangles, but they have to be mirrored. If you fold them both the same way, they won't lock together. It’s like trying to put two left shoes on. It just feels wrong and won't work.
Fold the top corner of the first strip to the right. Fold the bottom corner to the left.
On the second strip, do the opposite. Top to the left, bottom to the right.
Now, lay them across each other like a cross. You’re going to tuck the triangular flaps into the center pockets of the opposing strip. It’s a bit like closing a cardboard moving box. Once they’re tucked in, you have a sturdy, four-pointed star. This is your "rotor." It’s surprisingly rigid because the tension of the paper holds it together.
Punching the Center Hole
Precision matters here. If your hole is even a millimeter off-center, the spinner will wobble. Wobble creates friction. Friction is the enemy. I usually use a thumbtack to start the hole and then widen it slightly with the tip of a pen.
You want the axle (the toothpick or pen tube) to be snug but not tight. If it’s too tight, it won't spin. If it’s too loose, the spinner will tilt and hit your fingers.

Why Paper Spinners Actually Rank Higher for Fidgeting
There’s a tactile satisfaction to paper. It’s quiet. If you’re in a meeting or a library, a metal spinner with a ceramic bearing makes this high-pitched whirring sound that drives people crazy. Paper is silent. Plus, you can customize the aerodynamics.
When you’re mastering how to make a paper hand spinner, you can actually slightly bend the tips of the paper blades. If you angle them like a fan or a propeller, you can experiment with air resistance. Some people find that a slight "winglet" at the end of each blade helps stabilize the spin, though it might slow down the top speed.
The Bearing Problem
Let's talk about the center. Professional spinners use R188 or 608 bearings. We're using a toothpick. To reduce friction, you can rub a little bit of candle wax or graphite from a pencil onto the toothpick where the paper touches it. It sounds like overkill, but it makes a massive difference. You'll go from a 5-second spin to a 20-second spin just by adding that "lubricant."
Common Mistakes People Make
I’ve built dozens of these with my nephews, and the biggest fail is always the grip. If your fingers are touching the paper, it stops. Duh. You need spacers.
Take two tiny circles of cardboard or two small plastic buttons. Glue them to the toothpick on either side of the paper star, but leave a tiny gap—maybe the width of a fingernail—so the star can move freely. This gives your thumb and middle finger a place to hold without touching the rotating part.
- Using paper that's too thin (it just flops around).
- Forgetting to smooth out the folds (sharp creases lead to better balance).
- Making the center hole too large (creates an erratic, bumpy spin).
The "Ninja Star" or Shuriken fold is the most popular for a reason. It’s symmetrical. In the world of physics, symmetry equals balance. If one side of your spinner is even a fraction of a gram heavier than the other, the centrifugal force will pull it off-axis.
Advanced Customization and Physics
If you want to get really nerdy with it, look into "drag." A flat paper spinner has very little drag, but it also has very little momentum. If you’re really interested in how to make a paper hand spinner that wins "spin-offs," you should try the "weighted-edge" technique.
Instead of just two strips of paper, use four. Interlock them in a way that creates an octagonal shape. The more points you have further from the center, the better the rotational inertia. It’s why figure skaters pull their arms in to spin faster—moving mass away from the center changes the speed and duration of the rotation.
A Note on Safety
It’s paper, sure, but if you’re using a toothpick, be careful. I’ve seen kids try to sharpen the ends. Don’t do that. Snip the pointy ends off the toothpick once your "caps" are glued on. There’s no reason to have a weapon in your pocket.
The Cultural Shift Back to Analog
In an era where we’re all staring at screens 12 hours a day, there’s something genuinely grounding about making a physical object. It’s a "lifestyle" hack, honestly. Using your hands to fold, crease, and assemble something that relies on basic Newtonian physics is a great way to reset your brain.
Making a paper hand spinner is a gateway. Once you understand how the balance works, you start looking at other household items differently. Can you make one out of old credit cards? Probably. Bottle caps? Definitely. But paper is the purest form. It’s accessible.

Putting It All Together for the Best Results
If you've followed along, you should have a tight, interlocking paper star with a smooth center hole and some sort of spacer for your fingers. The first spin is always a test. Does it vibrate? Trim the edges. Does it stop too fast? Add a drop of wax to the axle.
Next Steps for Your Spinner Project:
- Source the right material: Grab some cardstock or heavy-duty scrapbooking paper for the best weight-to-durability ratio.
- Perfect the fold: Practice the mirrored triangle fold until the two pieces slide together without forcing them; this ensures the center is perfectly aligned.
- Lube the axle: Use a pencil lead to coat the toothpick axle—the graphite acts as a dry lubricant to keep the spin friction-free.
- Add "Hubcaps": Find two flat buttons to glue to the axle ends so your fingers don't accidentally graze the spinning paper.
The real trick is experimentation. No two paper spinners are exactly alike because the folds vary by a hair every time. Once you get a "good" one, you'll know. It feels smooth, it hums slightly, and it stays upright with almost no effort. It's a cheap, fun, and surprisingly educational way to kill an afternoon.
