Everything you need to build the project
from scratch:
Kids (Ages 4+): Kits range from beginner to advanced, depending on build complexity. Age grading may differ according to difficulty level.
Educators & Classrooms: Perfect for bringing abstract science concepts to life through hands-on learning.
Our DIY kits are designed to be both educational and fun. Our goal is to bring STEM concepts to life while helping kids get comfortable working with their hands. Along the way, they'll learn to problem-solve and confidently turn "It’s not working" into "Let me figure it out!"
Plus, the fun doesn't stop when the build is finished. Whether it’s our Aero Blast that kids can’t stop spinning or our Brighty which alternates between a flashlight and projector, our kits are designed for long-term utility and play.
Here are some friendly tips for when you're putting together our DIY kit:
- Check out our instructional videos! They're a super helpful guide to understanding the concepts.
- Read the instruction manual in detail since that contains vital information.
- Make sure to follow the instructions one step at a time. Each step is important, so don't miss any out!
- If you find a step a bit tricky, just re-watch the video or give our awesome customer service team a shout. They're always here to help.
- Try not to put too much force into the build process. If you are using too much force, there is something wrong.
- Double-check all connections are secure. We wouldn't want any sneaky leaks or short circuits.
- Test as you go along to make sure everything's working as it should. It'll save you from any possible re-work later on.
- Most importantly, enjoy the process! Remember, the goal isn't just to complete the project, but to learn and have a blast doing it.
