Snowflakes
This beautiful example of crystallized water is one of nature's hexagonal miracles.
Why are snowflakes hexagonal ?
Mr.Clever Dick may blurt out "Hydrogen bonding", but unless Mr.Clever Dick is conversant with molecular Physics or Chemistry, then he is totally oblivious as to what Hydrogen bonding is, or the molecular mechanics involved and why it results in tiny water droplets becoming a beautiful hexagonal snowflake.
A very interesting topic, look it up and improve your knowledge.
Hexagons in Nature are a very common phenomena. Why nature favours this geometric shape is unbelievable and in some cases a mystery. Only squares, equilateral triangles and regular hexagons can be fitted together so there is no wasted space.
Why do bees construct their honeycomb in connected hexagons ? They are only insects not mathematical experts who can calculate the optimum shape to construct a platform with minimum energy and waste of space. So why an "accidental" hexagon ?
Many crystals are hexagonal. The Giants Causeway in Northern Ireland, turtle shells, The Devils Postpile in California and further examples.
