Colliding water jets

When the pressure from the colliding water jets is equal, the water creates a bell. The strong hydrogen bonds between the water molecules make the jets come together and keep their form. By adjusting the pressure of the jet of water from the top tap, the position of the bell fountain can be changed.

Where can you see this in everyday life?

You can see the same phenomenon in a water jet, which can be found on a jet-ski. When the pressure from the top valve increases, it pushes the underlying water away.

Sustainable development

The water jet has a low submarine sound, which reduces disruptive sounds below the water’s surface. This improves the submarine environment for animals that use sound to communicate, such as whales and dolphins.
