You probably know by now that KiwiCo has a subscription line for just about every age, but did you know they also offer fun one-time boxes in their shop? They have interactive toys, educational kits that are similar to their monthly boxes, and even some fun holiday-themed boxes. As a mom, I am always intrigued by these boxes, but before I buy, I like to know exactly what I'm getting. This series will provide you with a review of some of these unique one-time boxes and hopefully help you make an informed decision about your own purchases. If there's a box you'd like to see reviewed from their shop, drop a line in the comments and we'll see what we can do!

This box was sent to us at no cost for review. (Check out our editorial guidelines to learn more about how we review boxes.)

This is a review of KiwiCo's Slime Circuits Kit (recommended for ages 9+) for $27.95.

First Impressions


This box was actually sent to us as part of our Tinker Crate subscription and I knew something that had to do with slime would definitely be exciting for my kiddos.

What's Inside the Slime Circuits Kit?

Everything was organized neatly inside the box with some materials in separate bags, making everything easy to locate.


This guide contained the instructions for making our circuit and our slime along with several different experiments for us to try once we had everything made and ready. There was also some educational information dispersed throughout which explained the science behind our project.



There were quite a few materials in this box. We had the main plastic pieces for our circuit, a battery, some LED lightbulbs, and several wires along with some foam stickers.


There were also all the materials for our slime including a mess mat, borax, glue, dye, spoons, stirrers, plastic cups, and plastic containers to store our slime in.

Assembling the Circuit


The first step was assembling the circuit. My daughter put the plastic guard around the tabbed base and then slide the wires through the holes on it. The LED light went in the center and the wires got connected to the various ends of it before using sticky squares to hold them in place. Lastly, the plastic dome went over top of it to protect the light. It was really very simple thanks to all of the cut outs and tabs that were already marked and cut out of the various pieces.

Making the Slime


Making the slime was very easy. We mixed up some borax and water in one cup and some glue, water, and colored dye in another cup and then slowly mixed the two to form our slime. Having made slime before, I was a little worried that it would be too sticky, but the texture was actually perfect!

She was definitely excited about how her yellow slime turned out!


After making our first color slime, we followed the same instructions to make another color. Since they sent red, yellow, and blue, the possibilities were endless, but my daughter stuck to the primary colors this time and chose blue for her next mixture.

Slime Circuits


Now it was time to test it all out! We separated one of our slime balls into two and then stuck in the ends of the wires from the battery and the circuit into them. The red wire lit up red, blue was blue, green was green, and when we used two different colored wires we got some different colors like purple. My daughter had a lot of fun playing around and exploring what each wire placement would do, and there were many helpful ideas in her booklet that helped direct her play! She thought it was all very cool!


She loved testing out the color mixing activity which was easy to do with the extra white wire they included.


I loved how easy it was to store our materials when we were done! Our slime went into separate plastic containers while everything else got tucked away inside our circuit and the lid twisted on to hold it all secure.

Value - Was This Box Worth It?

My daughter really loved this box and I thought it was a lot of fun, too. We still have enough supplies to make some more slime (although we did just about run out of glue) and we can use our new circuits any time, so I think that makes this a box worth having around for an educational rainy day activity! There is also some added value in the fact that we could use it to supplement our homeschool science learning!

Key Takeaways

I can see why this box was sent as part of our Tinker Crate subscription! It was very similar in that we had something STEM-related to assemble and then we had lots of ways to explore it and tinker with it. My daughter loved testing out the different ways to make her circuits light up and it was a great science activity to incorporate into our school day!

To Wrap Up:

Is this box still available? Yes, as of now the Slime Circuits Kit is still available! This was actually sent to me as part of our Tinker Crate subscription, so it may be part of yours as well!
