Making Ice Spikes in the Freezer

- 2023-11-10-

Ice spikes are ice tubes or spikes that shoot up or off at an angle from a container of frozen water in the winter, such as a bird bath or bucket. The spikes have the appearance of an inverted icicle. Ice spikes occur infrequently in nature, but you can easily and consistently manufacture them in your own freezer. This is what you do.

It is critical to use distilled or reverse osmosis water. Ordinary tap water or mineral water contain dissolved chemicals that may prevent or lessen the amount of spikes created by the water.You can use a bowl or cup instead of the ice cube tray. Plastic ice cube pans are useful because they include several small compartments, allowing for a short freeze time and multiple opportunities for spikes. Plastic ice cube trays are ideal for this project, although it's unclear whether the tray type or cube size improves the effect.

Pour the distilled water into the ice cube tray, place it in the freezer, and wait. Ice spikes can be seen in roughly half of the ice cubes. An typical ice cube tray takes roughly 1 1/2 to 2 hours to freeze. Because most home freezers are frost-free and blast warmer air over the spikes, they deteriorate and soften with time.

Pure water super cools, which means that it remains liquid after freezing. When it begins to freeze at this low temperature, it solidifies quickly. The freezing process begins at the container's edges because nicks, scratches, and defects allow ice crystals to form. The freezing process is repeated until there is only a hole near the center of the container containing liquid water. Because ice is less thick than liquid water, some crystals float to the surface and are pushed out, forming a spike. The spike expands until the water freezes.

Ordinary tap water or mineral water are less prone to develop ice spikes for two reasons. The first is that this water freezes at its normal freezing point. Because this is a far slower process than freezing from the supercooled state, solidification is more likely to be homogenous or to occur all at once across the ice cube. The ice spike cannot grow unless there is a hole in the ice. The other reason is that as water freezes, pollutants or impurities in the water get concentrated in the liquid. Solids, according to researchers, become concentrated at the developing point of an ice spike and prevent further growth.
