Ice-nine is a material appearing in Kurt Vonnegut's novel Cat's Cradle. Ice-nine is supposedly a polymorph of water (invented by Dr. Felix Hoenikker), more stable than common ice (Ice Ih); instead of melting at 0 °C (32 °F), it melts at 45.8 °C (114.4 °F). When ice-nine comes into contact with liquid water below 45.8 °C (thus effectively becoming supercooled), it acts as a seed crystal and causes the solidification of the entire body of water, which quickly crystallizes as more ice-nine. As people are mostly water, ice-nine kills nearly instantly when ingested or brought into contact with soft tissues exposed to the bloodstream, such as the eyes.
In the story, it is developed by the Manhattan Project in order for the Marines to no longer need to deal with mud, but abandoned when it becomes clear that any quantity of it would have the power to destroy all life on earth. A global catastrophe involving freezing the world's oceans with ice-nine is used as a plot device in Vonnegut's novel.
Ice-nine is a fictional solid polymorph of water from Kurt Vonnegut's Cat's Cradle.

Ice Nine is a first-person shooter video game for the Game Boy Advance. It was one of the final first-person shooters on the console. It was originally going to be a tie-in with the film The Recruit. However, this fell through, but the plot of the game remains unchanged. There was also a planned PlayStation 2 port, but it was canceled at some point in development.
The plot of Ice Nine is similar to the film The Recruit on which it was previously based. The player takes control of the recruit Tom Carter on a mission to stop an evil plot to steal the diabolical computer virus "Ice Nine". Over the course of the game, Carter unravels a conspiracy within the CIA.
Ice Nine was met with lukewarm reviews. It was praised for its above-average graphics and music, but criticized for its boring level design in comparison with earlier shooters such as Ecks vs. Sever. It currently has a 44% overall average on GameRankings.
