At the South Tyrolean Ahrntal, a snow cannon is now being used as a rainbow machine on hot summer days, spraying only a minimal amount of water.
The idea came about spontaneously, explained a spokesperson for the Klausberg ski resort: „Also haben wir uns gedacht: Schalten wir sie mal zwei Minuten ein, wenn es heiß ist.“ The background was maintenance of the system, during which the device had to be briefly put into operation. In the process, it turned out that the fine water mist could provide cooling.
Background: Maintenance as the trigger
„Wenn es nicht rausgespritzt wird, läuft es den Berg hinunter“, the spokesperson explained the technical necessity. So instead of letting the water run off unused, they simply sprayed it into the air on hot days. The result: a fine mist in which a rainbow becomes visible when the sun shines.
