Ice-Nine

Ice-nine is a fictional material conceived by author Kurt Vonnegut in his novel Cat’s Cradle. Described as an alternate solid form of water that is more stable than common ice, it is said to melt at 114.4° Fahrenheit (45.8° Celsius) rather than at 32° Fahrenheit (0° Celsius). When ice-nine comes into contact with liquid water, it causes the entire body of water to crystallize as ice-nine—with obvious far-reaching consequences. How did Vonnegut supposedly get the idea for the substance? Discuss
