What is Ice-nine?
{{Orphan|date=October 2011}} '''Ice-nine''' is a [[fiction]]al material. It was invented by [[author]] [[Kurt Vonnegut]] in his [[novel]], ''[[Cat's Cradle (novel)|Cat's Cradle]]''. Ice-nine was a special type of ice that would [[freeze]] at higher [[temperature]]s than normal ice. When dropped into other bodies of water, it froze that, too, which resulted in all bodies of water on earth being frozen by Ice-nine.<ref name=CC>{{cite book|title=Cat's Cradle|year=1998|url=https://archive.org/details/catscradle00vonn_0|author=Kurt Vonnegut}}</ref> ==References== {{reflist}} {{lit-stub}} [[Category:Science fiction technology]]
