For anyone curious about Ice 9: https://en.wikipedia.org/wiki/Cat%27s_Cradle https://en.wikipedia.org/wiki/Cat%27s_Cradle > Ice-nine is an alternative structure of water that is solid at room temperature and acts as a seed crystal upon contact with ordinary liquid water, causing that liquid water to instantly transform into more ice-nine. A substance called ice-9, with basically the same properties, makes a passing appearance in the visual novel Zero Escape: Nine Hours, Nine Persons, Nine Doors if you haven't heard of the book but remember the term from somewhere else. Admittedly, that's where I first learned about it but that said, there is a real substance called Ice IX but it isn't as interesting https://en.wikipedia.org/wiki/Ice_IX https://en.wikipedia.org/wiki/Ice_IX
