May Holiday

23 April 2022 - 8 May 2022
  • Workshop

During the May holiday there will be all sorts of things to do at NEMO. From 23 April until 8 May, there are additional workshops and demonstrations for you to enjoy, with special attention to water. Please note that NEMO will also be open on Mondays throughout this holiday period. NEMO is closed on Wednesday 27 April 2022 (King's Day).


During the May holidays, NEMO pays extra attention to: water. Visit the renewed exhibition Zuiver Water on floor 2. Here you will discover all the steps needed to get drinking water from the tap in Amsterdam. In workshops you can experiment with soap bubbles and have a look at Octomadness, a life-size zoetrope with a large moving octopus on top. Or is the octopus standing still?

Clear Water

Clean drinking water is not something that simply ‘happens’. With the right technology, it is possible to make almost all water clean enough to make it safe to drink. Water from the sea, the soil, or from rivers, for example.

Discover all the stages that have to be passed before drinking water comes out of Amsterdam’s taps.

Zoetrope Octomadness

This zoetrope (Klaas-Harm de Boer, 2014) is made of 64 unique 3D-printed and hand-painted figures. Due to the blinking light, short images are created. Your brain turns these images into a movie.
