The Explore Box - Letterbox Lab

The Explore Box Series

The little box of big ideas.

Is there a curious child in your family? A wee scientist with big questions? The Explore Box brings everything you need to inspire them with wondrous science experiments and hands-on projects.

  • enough materials for 1-2 children,
  • 3-4 exciting science experiments,
  • a “level up” sticker for your little scientist to wear,
  • a fully-illustrated 12-page instruction booklet,
  • link to online resources including video instructions.

We’re pretty confident that the Explore Box does just that! But if you don’t believe us, see what our customers have to say:

“Loads of fun and great that we both got involved together. The discoveries he made were told to everyone and now we are all much more knowledgeable. Really enjoyed recording in the booklet the results from the experiments. Much more in the box than I expected. Well done.

– Karen, mum of an Explorer

About the Explore Box

What’s in the boxes?

Each box in the series of twelve is different – we don’t like to be formulaic!

What you can definitely expect from every box is enough materials to complete 3-4 science experiments, activities and projects. Each box generally fills an afternoon with science fun, but we package everything up neatly so you can dip in and out throughout the month if you prefer.

The boxes also include a 12-page fully illustrated instruction booklet (featuring lab assistants Meg and Pico) that makes every step perfectly clear. If that’s not enough, we’ve filmed every experiment for you to watch! Your little scientist will also get a pencil to record their findings and a special achievement sticker to wear.

You can see a full list of the boxes with the experiments inside here.

“My science knowledge is pretty basic and my son is science mad so this was a great discovery for us both. We have lots of fun doing the experiments and he’s really excited every time he receives a new box. Thanks so much – genuinely one of the best things we’ve ever found!”
