Where does dust come from?
I know its tiny, minute particles of something.
Why is it that as soon as you dust somewhere, and leave it all shining clean, when you go back a short time later there`s a fine layer again?
Or, at least in some of our rooms at present there is!
Even when they`ve finished the work and gone,
for days after it seems to keep settling
and every time you turn round there`s another covering.
Does it stay invisible in the air?
Why does it cling to television screens?
Why is it attracted to computer screens?
And how the sun has a way of showing it up,
even on something you think is dust free.
