The sodium is very reactive with water. Exothermic reaction, lots of heat and fire. See the related question below.
How does the temperature of water affect the sublimation of dry ice?
cold water makes dry ice closer to its freezing point. so hot water makes dry ice sublimate more
Does water affect germination rate?
