Geyser

A geyser is a source that ejects hot water from the interior of the Earth. Our geyser is activated when you walk round it pushing the stick.

Walk around with the stick, and a stream is produced by the pressure that arises in the red half sphere. The stream corresponds in magnitude to a medium-sized geyser.

The word "geyser" is Icelandic and means approximately "the angry thing". It is the name given to hot sources that throw boiling hot water up in the air. Water in canals and hollow cavities is heated by the Earth’s inner until the pressure becomes so large that the water sprays into the air. The hot sources on Iceland provide a third of the country’s energy needs.
