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 LEGO® fidget spinner. The real ones spin for a longer time, but his version has a satisfying spin and is a fun LEGO® 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?

Hold the fidget spinner by placing one finger on each side.
Then use your thumb or finger to give it a spin!
Here are the bricks needed to build one:
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
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.
