Children discover science with stamps

Kinderen ontdekken wetenschap via postzegels

The Hague, 20 July 2015 – PostNL is issuing the ‘Discover Science’ stamp sheet in collaboration with Science Center NEMO. The brightly coloured stamps feature five scientific experiments that children can safely and easily do at home. A group of children carried out the experiments at the presentation of the stamps at NEMO.

The scientific experiments were on electricity, light refraction, static charges, vacuums and conductivity. These are also the five topics featured on the stamps. Jorn Dal of The Hague-based design agency SILO incorporated the idea of ‘opposite experiences’ in the illustrations he did for the stamps. NEMO presents experimental setups that visitors can work with interactively and that often have the opposite effect to the one you are expecting.

Doing experiments at home with stamps

After the children carried out the five experiments, PostNL’s Marketing Director Ludo Voorn presented the first stamps to NEMO’s Deputy Director Amito Haarhuis. “The stamps are fun and bright. A special addition is that you can also do the experiments step by step at home by scanning the stamps with the Cee app,” Ludo Voorn says. Amito Haarhuis is proud of the new stamps. “They offer the opportunity to discover science and technology at home. Furthermore, the stamps are a nice way of showing what NEMO is all about: learning about science in a playful manner.”


The ten stamps are marked ‘Nederland 1’, the denomination for items up to 20g in weight destined for mail within the Netherlands. The stamps will be sold in all Bruna stores starting 20 July, as well as via Collect Club. The stamps are also available at the NEMO Shop and online at The stamps are valid for an unlimited period.
