About this event
The Atomium is given over to researchers for two days, with the Saturday reserved entirely for the general public: a climate quiz, cities built in LEGO, light and colour experiments, origami, wind tunnels and water rockets, plus film screenings, debates, a photo exhibition and open conversations with working scientists. Children are expected to take part rather than watch.
