[日本語がまだありません。書く暇が出来たら書きます。^^;] People who attended the event may have noticed that the organizers seemed to have set up equipment to measure something. What they were doing is measuring the temperature, wind and height of water being thrown.
After water has been thrown and if there was a breeze (which there was), then the temperature should temporarily cool down.
I think the heat being generated by the excited men alone prevented any type of temperature cooling.
