Welcome to the water flea

"Splash, splash - dive down with us!"  The children's museum under the roof is showing its special exhibition "HaZweiOohh! Welcome to the water flea". Together with Daphne the water flea, children aged between 4 and 12 can discover the secrets of water.


What does the cool water consist of? How much of it is in the body? And why do people have to constantly refill it? Water flea Daphne knows the answers and invites you to discover water as the most important food and habitat in exciting hands-on stations.

Guests young and old can help create a colorful pond world, dress up as a carp, newt or frog or dive into the cozy reading corner.

For children between 4 and 12 years old



No registration needed.
