First Impressions

I thought that making our own conveyor belt was a pretty cool project and I knew immediately that I would be giving this one to my kids so that they could use it for some pretend play! While it's a bit small, it will work perfectly for toys so they can have their own store at playtime.

What's Inside This Box


Our Tinker Zine is full of educational information about conveyor belts. I was super impressed with how many different types of conveyor belts they were able to show us! There was also an activity at the back that taught us how to make our own conveyor belt cinema.


The directions for our project come on a separate sheet with illustrated steps broken into different sections. They always include helpful troubleshooting information as well.

Part A: Assemble the Base


The first step was to assemble the base. They provided several wooden pieces, some plastic caps, rubber bands, cardboard tubes, and both a paper and a fabric belt.


They also provided a motor, a battery pack (pre-filled with batteries), some foam adhesive, stickers, a weighted ball, and even an extra fabric sheet in case our other belt doesn't work.


First, I added the plastic caps to the two cardboard tubes. Then I placed the side pieces on holding them in place with the rubber bands. Then I attached the motor to the side using an adhesive foam piece.


Next, I added the paper and the other tube before closing up the other side.

Part B: Complete the Conveyor


To make the actual belt I laid out the fabric strip on the table then added one of the adhesive strips to the end and folded it up around the base. Then it was time to wire up the motor to the battery pack.

Part C: Make the Tumbler


The tumbler was easy to make; I just added the foam pieces to the orange paper and folded it up around the weighted ball and used the stickers to close it up.

Part D: Balance the Tumbler


I added the dowel underneath the jagged side of the belt and then placed the tumbler on top and turned it on.

The belt worked nicely and it was fun to play around with the tumbler at different heights to watch it move! It was such a simple addition to the project, but an effective one!


Finally, we added the paper belt to it and completed a fun challenge! The goal was to try and mark the teal circles and avoid the red ones. My daughter was up to the challenge! Then she added the tumbler too to make it even more interesting.

We learned so much about conveyor belts with this box and made a working belt that will be perfect for some pretend-play for my kiddos. The materials were high quality and they included everything we needed so I think this was a great value!

Key Takeaways

My daughter and I both enjoyed testing this one out! The tumbler and the circle challenge made it even more fun. As for the belt itself, it was super easy to build thanks to the clear instructions they provided!

I am a homeschooling mom to 4 kids; 1 girl and 3 boys. While I have been reviewing boxes since 2018 and I love the luxury of trying new products, I'm also balancing it out by dabbling in a little bit of homesteading, too. We now have 4 chickens and a rabbit and my sourdough starter is going strong! I love learning about new brands and sharing the great things I find with others in hopes that they find something new to love or to fit their needs!
