Have you heard of fidget spinners?  Originally introduced as a fidget tool for kids with ADHD or autism spectrum disorder, they have exploded in popularity with kids everywhere!  My boys heard about them from neighbor kids and wanted one of their own, so we ordered one from Amazon.  I’ve gotta say – it’s a fun little gadget that demonstrates some neat properties of physics!

Aidan (age 13) has been working for a couple of weeks to design a fidget spinner out of LEGO® bricks.  The real ones spin for a longer time, but his version has a satisfying spin and is a fun build!  Challenge kids to build one with our design or to create their own.  Can they figure out the best way to distribute the weight and reduce friction between the moving parts?

How to Build a LEGO Fidget Spinner

Hold the fidget spinner by placing one finger on each side.

LEGO Fidget Spinner

Then use your thumb or finger to give it a spin!

LEGO Fidget Spinner

Here are the bricks needed to build one:

LEGO Fidget Spinner

Start by putting a 4 x 4 round plate on both the top and bottom of a 6 x 6 round plate.  Slide one of the 2 x 2 round tiles (with a round hole) onto the axle.  You’ll need an axle that is 3 studs long with a stud on the end.

Part number for 2 x 2 round tile with hole:  15535

Part number for axle:  6587

LEGO Fidget Spinner

Place the turquoise round plate on the axle.  Add another 2 x 2 round tile to the axle.  Attach it to the dark red round plate.

Slide a 2 x 2 round plate (with an x shaped hole) onto the top of the axle.  Leave some space so that the spinner is free to turn.

We found that our spinner would spin for a longer time if we added arms.  The additional weight seems to give the spinner more momentum.

Place a 2 x 3 plate under the turquoise round plate.  Then add a 2 x 2 plate and another 2 x 3 plate.

Add all four arms, and your spinner is ready to go!

To spin it, place one finger on each side as shown below.

Have fun building!  Here’s a video that shows Aidan’s spinner in action, and he also demonstrates how to build it.

        They reduce stress and the amount of time your kids pay attention in school. Trust me, I'm a student myself

          THANK YOU - you know how many stores I've gone to in the last few days looking for one of these fidget spinner things? Ack! They are sold out everywhere, and we ordered one on Amazon but it said it won't be here until mid-June (even though when I initially ordered it it said next week). So now my 7 yr old son is upstairs gathering his legos to make this one and is so excited! :-) (Things sure were much easier in the days before they knew what was popular!)

            I can't believe Amazon is sold out! We bought one a few weeks ago while they were only mildly popular. Then all of a sudden it exploded! I hope he was able to get the Lego version to work!

                  I did not have the large round plate ether so i built it with 4 4/2 plates and put 2/1 plates on the top and bottom of one side and put the 4 arms and put those in the place of the large circle.

                      The turquoise circle came in one of the yellow classic tubs - I can't remember which one. The other ones are from random sets! We like to use Brick Link for ordering individual pieces. http://bricklink.com

                            ToyBurg has all the parts for $1.23 if you are making 6 or more of them. Otherwise you might need to pick and choose stores.

                                      The spinners have exploded in popularity at my kids school as well, every child "has to have one" I personally don't see the wow but kids are something else lol
                                      For parents having a hard time finding them...try your local swap meet or flea market, they are available in abundance there for about 5 bucks. Local 7-11 stores carry them for about 8 bucks.
                                      My son got a batman spinner for $5 and a light up one for $8
                                      Build your own is going to blow him away. I can already see my husband pulling out ball bearings to supe it up.

                                                thats the part i can't find (and i was also thinking it would be super awesome to order the parts to make multiples of these, make a printable direction sheet, and give them out as party favors!) but when i search on the lego.com pick a brick section, that number doesn't bring up anything! Had this same problem trying to look up some parts for a lego fidget cube i saw on another blog that had several obscure technic pieces I don't have. Part numbers for all of them, but can't search for them on lego.com? have to awkwardly search by category. Where are these part numbers coming from?

                                                  Rachel, the part numbers are located on each LEGO brick. They are very tiny! I don't know why that part number isn't coming up on Lego.com. I agree that their system is cumbersome. Here's a link to the part on Brick Link. I prefer to order from Brick Link because orders arrive much more quickly. It's similar to eBay, but with LEGO bricks. https://www.bricklink.com/v2/catalog/catalogitem.page?P=15535&name=Tile,%20Round%202%20x%202%20with%20Hole&category=%5BTile,%20Round%5D#T=C

                                                        My kids had so much fun building these! They still begged for store bought spinners and I finally caved. To keep the spinner fun going I created a board game that uses the spinners. We've had so much fun playing it. Its available to download on my blog, http://www.namesakedesign.com/2017/05/are-fidget-spinners-driving-you-crazy.html, if anyone is interested.

I went to Bricks and Minifigs today to get all the pieces to make it and they said this last week your tutorial has become so popular that they are all out of those round pieces! I ended up finding a different way to make a fidget spinner that I published on my site today but I still link back to you because yours is great. Good job!

                                                                        Reply

The only trouble is you can not get the Lego to make the spinner. If you have ore resources than I know of it would be great to share. The Lego site does not have all the pieces for sale to do this project.

                                                                          Reply

You can find all of the pieces there! Just keep in mind that the site is made up of many different vendors, like eBay.

He was being offered money at his school to purchase the spinners. His design is almost the same using less bricks making it somewhat lighter and having more spinning action. But great job to Aidan and all the master builders out there :))
