+This mod adds an ice machine, ice bin, and ice cubes.
+
+To make the machine work, place it on top of an ice bin and turn it on. It will slowly produce ice cubes and eject them into the bin. The cubes can then be crafted (9 at a time) into ice blocks. If technic is installed, these ice blocks can then be ground into snow if desired.
