Why do fans have 3 wings?

Perhaps, the 3 wings will cut more air and hence force the air to flow downwards, meaning we get more air with three wings. Four may make it more heavy (consuming more energy) while 2 may reduce the amount of air forced downwards.

why does not honey get spoiled?

Liquid honey does not spoil. Because of its high sugar concentration, it kills bacteria by osmotic lysis. Natural airborne yeasts cannot become active in it because the moisture content is too low. Natural, raw honey varies from 14% to 18% moisture content. As long as the moisture content remains under 18%, virtually no organism can successfully multiply to significant amounts in honey.
