The snow level in the Snow Chamber (snow-covered area of Snow City building) is maintained at 400mm in depth. Up to 150 tons of snow are required to cover the snow grounds and about 10 – 15 tons of snow is made each week to maintain this snow level. The amazing fact is: all this snow is produced on-site using a specially-designed snow gun!
Observe the following snow-making stages:
- Water is atomized using high-pressure compressed air
- The water arrives at the snow gun and is pushed out the special nozzles at the end of the barrel
- Liquid Nitrogen (which freezes at the amazingly low temperature of –196 degrees Celsius) is also passed through the snow gun
- The extreme cold of the liquid nitrogen snap freezes the atomized water into powder-like snowflakes.
The secret formula?
One ton of liquid nitrogen + one ton of water = one ton of snow!
This is only one of the amazing facts on snow and cold temperature, which you will discover at Snow City. Be sure to visit our Enrichment Programme page for more details on other interesting and fun topics.
