We don't typically think about the procedure required to form ice. However, behind this seemingly simple compound is a very complicated scientific process. When cooled, water forms crystals that eventually bond into a solid piece of ice. With modern conveniences such as refrigerators with built-in ice makers, the availability of ice is often taken for granted. Making ice without a refrigerator takes a bit of ingenuity; however, it can be easily accomplished with the right outside temperatures or the use of alternate appliances.
Place water in an ice-cube tray or other container.
Check the outside temperature to ensure it is below freezing (32 degrees Fahrenheit).
Place ice-cube tray outside in an area where it will not be disturbed.
Allow water to set outside for at least four hours or until completely solid.
Fill ice-cube trays with water.
Place trays into stand-alone freezer.
Allow water to freeze for at least four hours or until completely solid.
If you are near a frozen pond or lake, use an ice auger to bore into the frozen water.
Cut the ice away using a chisel, hammer or large saw.
Pull up ice block with ice tongs.
Chip away at ice block with an ice pic to create cubes.
