Understanding Ice Spikes
The formation of ice spikes occurs when a frozen layer of water develops from the outside in, allowing water to expand as it freezes. Initially, freezing starts at the surface, creating a shell while liquid water remains beneath. As temperatures drop further, the water beneath transforms rapidly into ice, forcing water upward through openings, thus forming spikes. Conditions need to be precisely aligned – typically around 20 degrees Fahrenheit and with pure water – to ensure the formation of these intriguing structures.
