This survey about water, marriage two abundant elements that, once combined, make stable couple in strange relationship. focus survey just how strange this coupling is.

By applying an electrical charge (such as from solar panels), water molecules can be split into their hydrogen and oxygen components (H2O). These gaseous elements can be compressed and stored in separate containers. The two components can then be "burned" as fuel to provide energy such as to produce electricity or power a car with water as a byproduct. This is the ultimate clean and renewable energy.

Water can be cooled below its freezing point without solidifying, a phenomenon where it can instantly freeze when disturbed.

Water is the only substance on Earth that exists naturally in three forms: solid (ice), liquid (water), and gas (steam).

Most solids sink in liquids. Because ice is less dense than liquid water, it floats, a property essential for aquatic life in cold climates.

Water is the ultimate renewable resource. The water you drink today is the same water that existed on Earth for billions of years, meaning some of it was once drunk by dinosaurs.

Most items contract as they get colder and freeze. Water expands when it freezes. This expansion is an unusual property that causes pipes to break when the water inside freezes then expands. This also can cause rocks to split and concrete to crack.

This survey is about water, a marriage of two abundant elements that, once combined, make a stable couple in a strange relationship. The focus of the survey is just how strange this coupling is.
