My last post was about the Booster Bricks subscription we bought our kids for Christmas. It is not just a box of random Legos though. The box includes challenges as well as an online Facebook group to participate in: weekly challenges, builds, and games.

This past weekend’s challenge was to build a Lego Carousel. Two of my boys, Matthias and Ian, worked pretty hard on it so I thought I’d post about it here.

For Christmas, we also bought our kids one of the largest Technic sets currently available: The Bucket Wheel Excavator. At almost 4,000 pieces, this is a huge set. We have to confess that we bought it mostly for the pieces. My boys used some of those pieces in their Carousel, which is why it looks a bit skeletal.

Matthias and Ian used a medium motor to power the Carousel. The gear assembly is pretty simple. The circular yellow pieces form a large gear.

You can see the gear and motor assembly inside the walls in the picture above. The switch is located outside the walls.

The Carousel sits on the small gear attached to the motor as well as 3 flagpole pieces that help keep the Carousel level but still allow it to rotate.

I was really proud of my boys for keeping at this build. They had no instructions and only a little bit of help from Josh. He helped them figure out how to downgear the motor so the Carousel wouldn’t spin too fast.

Here is a quick video of their Carousel in motion!

They didn’t mess with the design element too much but that is ok with me. I’m more interested in their learning the mechanics of it. Design can come later!
