Tirohanga Whānui：
Ka whakamahia e te rūma whakaora-mate te hauota wai (-196°C) hei pūtake makariri. Mā te rehu i te hauota wai kua mimiti, ka taea te whakaheke tere i te pāmahana i roto i te rūma ki te -110°C~-160°C. Ka honoa te hauota taiao parakore ki ngā rama āhuarangi karapoti hei hanga i tētahi wheako takai 3D.
