Can water be man made?
While making small volumes of pure water in a lab is possible, it's not practical to “make” large volumes of water by mixing hydrogen and oxygen together. The reaction is expensive, releases lots of energy, and can cause really massive explosions.

How much water is frozen in Antarctica?
The Antarctic Ice Sheet covers an area of almost 14 million km² and contains 30 million km³ of ice. Around 60% of the world's total fresh water (90% of the world's surface fresh water) is held in the ice sheet, equivalent to a 70m rise in global sea level.
What percentage of the Earth's water is frozen?
About 71% of the Earth is covered in water. Most of that is in oceans, rivers, and lakes, but some is frozen in the Earth's two ice sheets. Those ice sheets, which cover most of Greenland and Antarctica, only contain 2% of the world's total water supply, but a whopping 70% of the Earth's fresh water. Scientists estimate that if the Antarctic Ice Sheet—the larger of the two—melted, sea level would rise by around 60 meters (200 feet). Not only that, but it could affect the weather: a study showed that less sea ice in the Arctic causes rainier summers in western Europe, and another study suggests that it's causing more extreme heat waves in the United States and elsewhere. And counterintuitively, melting ice also causes more melting ice. A 2016 study found that a shrinking in the Greenland Ice Sheet causes what are known as "blocking events," where high-pressure systems park themselves on top of one area for days or even weeks. This brings warm, moist air that heats the surface below and causes even more ice to melt. Explore the relationship between polar ice and climate change in the videos below.

Is the ice in Antarctica salty?
Because of the much higher density of brine than of seawater the brine flows straight down through the water and forms lakes in any depressions on the seabed. Thus ice formed by freezing of seawater found around the coasts of Antarctica is also free of salt.
Why does salt water not freeze?
The reason for this is tied to the sodium chloride ions in the salt water solution shown here as blue and red circles. These charged particles disrupt the balance of the molecules causing the number of water molecules that can hook onto ice molecules to decrease. Water thus freezes at a slower rate.
