KiwiCo Review: Kiwi Crate for 5-8 year olds – DISC LAUNCHERS

Creative homeschool STEM fun with the Kiwi Crate Disc Launchers box and learning about physics through play!


The science for this box is learning about physics and inertia. What I love about KiwiCo is how engaging they make learning about physics and how easy they make it for kids to understand. The comic strip for this box features the regular characters having wagon races with their soft toys – when one of the wagons is stopped by a rock, the stuffed bunny goes flying! They learn that not only is inertia a resistance to a change in force – movement – but also that seat-belts are really important protective features.

The Explore magazine gives lots of fun ideas of ways to explore inertia at home – from attempting the ‘pull tablecloth from beneath a plate’ magic trick, to watching what happens when you stop your own wagon suddenly. We found that we could easily repeat the concepts in the comic strip by using Lego vehicles and mini-figures, or by putting little balls into one of our HotWheels that looks like a supermarket trolley.

The main engineering build for this crate is building a Disc Launcher (reminiscent of a clay bird launcher) and there are enough materials to build two of these. There are a heap of wooden discs to launch, and these can also be used for homeschool activities as counting, coins, and whale food.

The disc launcher comes with ideas for games – such as knocking down skittles (rainbow ones included) or playing a version of curling using the scoring mat (included).

The secondary project (art) is using your imagination to make things out of air dry clay (pack included). We used the three colours provided (red, yellow, blue) to make archways, a goalie, and lots of multi-coloured balls. We found that we could get cool multi-coloured swirling colours when lightly combining and a sort-of purple when they were really thoroughly mixed. Our creations then created a kind of obstacle course for the disc launcher. It’s worth noting that air dry clay starts as a very soft malleable material; after 24 hours drying it could readily be played with but was also still able to be changed into new forms. You may want to give it a full week to dry and harden (if the kids are willing to wait that long).


This is not a paid review. I spent a lot of time searching the internet to find out more information about the Kiwi Crate and Atlas Crate boxes before deciding to try them and found the blog posts / photos that people shared were really useful!

What I like about the Kiwi Crate kits is that they use a combination of Science, Technology, Engineering, Arts, and Mathematics to explore a concept or idea. There’s no obligation to sign-up in an on-going capacity so it’s easy to tie them in with birthdays / Christmas; the boxes are quite compact so they also store easily in a cupboard for bringing them out on a rainy day. Mind you, this only works if you spot the package on the door-step first – children become quite adept at recognising the green Kiwi Crate box and screaming with delight at it’s arrival!

The boxes are sent randomly so there’s no way to know what will come in the future; however, you can log-in to your account at the start of each month to see what box has been selected. Your box history is kept which means that even if you cancel and then pick-up again the following year they can make sure that you aren’t sent repeats of boxes.


The Kiwi Crate is aimed at ages 5-8 years. It comes with a copy of the Explore magazine which opens with a fun comic about Steve the Kiwi and his friends. [As a side note, these are made by an American company despite the use of our New Zealand native bird]. These comics are really approachable for younger kids and a great way of exploring the concepts being introduced in a relateable manner.

The Explore magazine provides a range of information on the topic, it might include some simple games or tricks to try at home, and provide ideas for additional crafts / activities using simple materials. It also has a sticker [unique to each box theme] to put on your Kiwi Crate chart.

The box also includes an instruction manual and the materials that you need to build the main craft. Generally, there are two activities to do – one that is more art related, and one that is more mechanical engineering. What makes the kits special, is how well crafted the engineering components are. They really are designed for the intended age group so that they can either build themselves or help assist an adult. There are handy visual images and checkpoints to make sure that things are aligned correctly. There is no super-bonding-fingers-together wood glue to use with these projects (which makes them great for highly sensory children); instead parts come with double sided tape finely engineered on so that you just need to remove the backing strip of paper.
