A monthly educational and fun-filled science kit for children aged 6+

  • Receive an exciting monthly delivery of 3-5 experiments
  • Everything you need to have fun playing with science, straight through your letterbox
  • Incredible experiments from all areas of science, from chemistry to dinosaurs
  • Science kits reinvented to be more fun, more educational and more convenient
  • Playing with science is made easy with comic-book instructions and online extras
  • Characters Meg and Pico provide helpful explanations along the way

Celebrate the wonderful world of science with The Explore Box from Letterbox Lab - the monthly subscription box that delivers everything required for youngsters to make astonishing discoveries about the universe from the comfort of their own home. Curious little scientists aged 6+ will receive an exciting monthly delivery of 3-5 experiments, plus multiple suggestions for extra activities to keep the fun going!

The boxes are designed to work in a series, with each box building upon the principles introduced in previous boxes for a truly eye-opening discovery journey! The first box is called Hidden Rainbows and provides an introduction to scientific methods and, more importantly, the joy of discovery! In Hidden Rainbows, children reveal hidden colours in inks, sweets and - thanks to their own customised rainbow glasses - light! Plus, cheeky lab assistants, Meg and Pico, provide helpful explanations and thoughtful questions to support learning from key stage 2 and onwards.

As children work their way through each box, their achievements are rewarded with a new “level up” badge, as well as a certificate and exciting gift in every third box.

The Explore Box is recommended for children aged 6+ under adult supervision. It contains small parts that pose a choking hazard for children under 36 months. The science kits were developed to fully conform to the Toy Safety Directive and do not contain substances that cause harm.
