Water is a very underrated, yet complex compound, but is also an easy start point for sciences; Water can be very damaging, it causes damp, it causes structural failure and structural damage through salt hydrolysis, yet water can conduct electricity through salts (osmosis), but water and electricity can also start fire, water is an important element in sulphuric acid, which, as those who know, will know that sulphuric  acid is a powerful acid that can dissolve solid concrete.

But we humans must have water to provide life, to provide plasters, renders, paints & finishes. (Habitat)  All creatures and vegetation need water and moisture, and again we need them! Yet most people don't even understand the fundamentals of water.

When gold freezes, science states the the density increases, so that gold actually gets smaller in size. When water freezes, unlike any other known material on earth, it expands,  (by approx 10% in volume). Due to the hydrogen bonds  which is called the "Mpemba effect", forming a hexagonal shape as rhey freeze. Furthermore hot/boiling water freezes faster than cold water. So, all this molecular activity connected to temperatures means that when ice thaws, it contracts again by 10% in volume, so be inquisitive and you'll learn that polar bears can swim!

 

but never forget: building's easy!  Any Armchair expert will tell you that!
