According to our research, not all aqua solidifies in the same way. Even though water molecules react to ice, in the same way, the full effect will take longer to show. When compared to water straight from the tap, the surface of a pure liquid, such as distilled or filtered water, will freeze the fastest. The most intriguing aspect of this problem is that simmering or plain hot water tends to solidify faster than cold water. Unfortunately, science has yet to find the correct answer to this question, and there is no data to indicate what this effect is related to.
