H2Ooh!
H2Ooh! – Water games

HOW TO PLAY
Free admission during all visiting hours.
The exhibit
Imagine being able to create a whirlpool and observe the power of this extraordinary element up close.
Or playing musical instruments using only the force of water, making balls run against gravity, observing that water is movement, energy and transformation.
These and many other exciting experiences are possible thanks to H2Ooh!, an exhibition dedicated to one of the fundamental elements of life, water, which becomes a key to discovering the principles that govern nature and physics through play.
H2Ooh!, also known as Water Games, is one of the symbolic installations in the history of Explora, which, since its opening, has enchanted children with the charm of science turned into play.
Today, thanks to the Explora Cresce project, supported by Fondazione Roma, the exhibition has been revamped and is now even more spectacular: located in the centre of the museum, with its nine stations, it combines fun with scientific discovery, while highlighting the role of technology and innovation.
The workstations
- Dams: experiencing the force and speed of water
- Communicating vessels: understanding balance and the principle of connection
- Water as energy: producing energy from renewable sources
- Pouring: playing with different shapes, objects and containers
- Inclined plane: discovering gravity in action
- Vortex: observing a complex natural phenomenon up close
- Playing with water: creating melodies through water jets
- Air pressure: testing an invisible force
- Hydraulics: designing and transforming ever-new circuits
The game promotes the development of scientific and physical concepts through direct experience of phenomena that children can produce simply by manipulating water and objects such as pipes, containers, tools, and much more.
It stimulates the ability to observe, investigate, experiment, and find solutions.

That’s how you have to be! You have to be like water. No obstacles – it flows. It finds a dam, then it stops. The dam breaks, it flows again. In a square container, it is square. In a round one, it is round. That is why it is more indispensable than anything else. Nothing in the world is more adaptable than water. And yet when it falls to the ground and persists, nothing can be stronger than it.
