Christmas holidays

There is lots to discover at NEMO Science Museum during the Christmas holidays. Get started in extra workshops, be amazed by the Chain Reaction and do winter experiments in the Laboratory.

  • 20 December 2025 to 4 January 2026
  • All ages

Open throughout the holidays

NEMO is open every day, including 25 and 26 December and 1 January.

Winter in the Laboratory

Why does slippery ice disappear from the road when we spread gritting salt? How do fireworks shoot so high into the air on New Year's Eve? And how can you tell if the almond paste in your stollen or pastry is really made from almonds? Find out in the Winter Lab. Lab coat? Check! Safety glasses? Check! Let's get to work!

Welcome to the world of action and reaction

  • Chain Reaction

    A spectacular demonstration of potential and kinetic energy. Discover action and reaction, cause and effect in the Chain Reaction.

  • Build your own chain reaction

    Knock over dominoes, set a seesaw in motion, launch a catapult and ring a bell.

The Baby of the Future

Just imagine that scientists could create egg and sperm cells from your blood, or from your urine. These cells could eventually grow into a baby. This would mean that anyone could have a child. Young or old, man or woman, sick or healthy. What would you think of that?

In a temporary exhibition set up by the Rathenau Institute in NEMO, you can discover what might be possible in the future with cells created in the laboratory. Share your opinion by placing stickers. Recommended age is 12 years and older.

Extra workshops

  • Make a short film

    Sketch a comic strip and set it in motion with a zoetrope.

  • Build a sorting machine

    Discover how smart machines work by building your own sorter that separates large and small objects.

  • Play with reflections

    You usually use a mirror to look at yourself. You can also use it to conduct all kinds of surprising experiments.

  • Guess the device

    Your alarm clock, toaster, telephone: would you recognise everyday devices if they were taken apart?

  • Make the lamp light up

    Get started with electricity and make an electrical circuit. Can you make the light blub glow.

Demo: For Sure?!

Discover how you can prove that something is really true and what happens when you put your assumptions to the test. Through impressive and interactive experiments, you will learn how scientists work step by step, with questions, predictions and experiments.

Science Live: Watch, guess, connect

Utrecht University is researching how you understand others. In this study, you can play two games.

  1. Can you guess what someone else likes just by watching their actions? And also when there is a risk involved in those actions? Play along and become a real preference detective!
  2. How do you feel about meeting new people? In this game, you will discover what might help you feel safe and secure in new situations.
