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. We’ve done all the hard work prepping, filming and gathering materials, so you and your little scientist can open the box and have fun making discoveries together.

Each box contains:

  • everything you need (but still fits through most letterboxes),
  • 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.

“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!”

– Jane

“This box was aimed perfectly at Miss A’s age range. She was completely engrossed in the experiments throughout and can
not wait for the next box to arrive! … “

“The box is great value for money…the quality and presentation excellent…build up your own Science kit.”

Patricia (Four Little Girls… The Mummy Memoirs)

“Letterbox Lab is such a terrific bunch of activities to do every month! They are a wonderful creative (and often happily messy!) way to introduce young children to scientific principles.
