🟨 CuriosiTOTS Jumbo (yellow box) is suitable for 4-6 years

🟪 CuriosiTOTS Nano (blue & purple box) is suitable for 4-6 years

With all our boxes we encourage grown-ups to offer their services as trusty lab assistant, and it’s up to you and your cadet what activities you do together. All we ask, is that you follow our safety instructions.

Yes, BUT they are not intended to feel like school! We want kids to be exploring and thinking, not just learning fascinating facts. So we have linked each activity to the primary curricula for England, Scotland, Wales and Northern Ireland, with a very large dash of flair and creativity!

All of our activities are with your child’s safety at the top of our list of must-haves. We don’t let anything out of CBHQ without making sure it’s fully compliant with the latest Health and Safety legislation. Some of our boxes contain food (like Bake Off Lab and Healthy Me) so please read the details of the box before you check out. 

Science and sustainability go hand-in-hand at the Curiosity Box, and as scientists, we want to make this world a better place, not one littered with junk.  So we have a simple but strict policy:

  • Our packaging has always been compostable corn starch or sustainably sourced card.
  • Our supply chain is as ethical as possible, and minimising carbon by sourcing as much as possible from local suppliers.
  • The contents of the box are all sourced with the environment in mind.  We use compostable cups and straws, eco cotton buds, eco glitter and reusable containers wherever possible.
  • We challenge our Curiosity Community to find creative ways to use their box when they’re done with the activities!

There are 24 different themes:

1. Amazing Earth9. Dinosaurs and Fossils17. Mind Blowing Microbes
2. ATOMIC10. Electrifying Electricity18. Potent Potions
3. Bake Off Lab11. Escape Room Challenge19. Seaside Science
4. Bees and Pollinators12. Fire & Ice20. Space
5. Clever Cells13. Healthy Me21. Spooky
6. Code Breakers14. Incredible Creatures22. Sublime Slime
7. Cool Crystals15. Light Fantastic23. Super Senses
8. Cosmic Blast Off16. Magnificent Magnets24. Think & Tinker Engineering
  25. Woodland Wonders (COMING SOON)

Not at all! We’ve lost count of the amount of times we’ve had parents say “I’d have loved science if I had’ve had something like this when I was a kid!” Each activity comes with:

  • a clear set of instructions
  • a simple explanation of what’s going on
  • “How To” videos to help you with any sticky bits (sometimes literally!)

STEM is simply an acronym and stands for Science, Technology, Engineering and Maths. You might also come across STEAM which is just Science, Technology, Engineering, Art and Maths.

Our Jumbo Boxes are chocka full of experiments and collectable lab equipment. These boxes are everything you need for a home science club. Each Box contains about 4-6 hours of activity time that can be broken up into smaller time chunks. The dimensions of this box are: 32cm W x 34cm L x 10cm H


Our Nano Boxes are letterbox sized (they are made to fit an average UK letterbox) and contain about 2 hours of activity time. The experiments are still awesome but we haven’t perfected our shrink ray yet so some of the bigger bits of kit are only available in the larger sized boxes, The dimensions of this box are 32cm W x 23cm L x 3cm H

We include all the specialist equipment and for the most part, all the other bits and bobs you need. But there are a few things that we can’t include because we aren’t allowed to ship them because they’re too large/fragile (like an egg!), or they’re things that you’re bound to have at home, like bowls, spoons, scissors for example. 

Yes you can. When you have picked your box and are ready to check out you can add a different delivery address to the billing address.

Subscription costs vary depending on how many months you buy up front and the size of box you want (costs below inc p&p):

  • Pay as you go monthly: £14.50/month for the letterbox sized box and £24.95/month for the large jumbo box.
  • 3, 6 and 12 month subscriptions offer bulk buy savings with a 12 month subscription resulting in a cost of £12.50/box for the letterbox sized box and £22.16/box for jumbo.

Single boxes cost £14.95 for the letterbox sized box and £26.45 for the jumbo box

Our boxes have loads of stuff in them! Lots of the activities can be easily shared and done with multiple children together. Where they can’t be shared, they can be repeated, so siblings can take turns!

We do ship outside the UK! Look for your country on the dropdown list at the checkout and if it’s there, we ship there. The cost of shipping will be calculated when you enter the shipping address.
If your desired destination isn’t on the list please do get in touch with our Head of Happiness, Claire, who will see if we can work something out for you!

Every brilliant scientist needs a helping hand from time-to-time! Just drop us an email or call us 01865 546145 and we’ll help you and your cadet get your activity or experiment back on track.

Don’t worry, just drop us an email at: or call us 01865 546145, and we’ll sort it out.

All our orders are sent by Royal Mail 48 which includes a tracking number so we can see if your order is still on its way. We suggest allowing up to 5 business days, but after that drop us a line at or ring on 01865 546145, and we’ll help you track it down.

Don’t worry, we’re totally prepared. Let us know by emailing us at or by calling us on 01865 546145. We’ll log it, and send you a replacement straight away. We also recommend that you dispose of the box safely. We don’t include anything hazardous in our boxes but, we like to play it safe so if your box is leaking, please wear some safety or rubber gloves before handling the contents. All the packaging is either recyclable (instruction cards and box) or compostable (the little bags that we use the package each activity up). If you get the Jumbo or Curiositots boxes you might be able to salvage the collectables! 

All our experiments and activities are designed and put together by our team of thinkers, tinkerers and testers right here in the UK. Our team is made up of bright young researchers and engineers from The University of Oxford, people who have worked in schools and of course lots of mums!
