Tuesday's Riddles

1) Taller than the tallest tree,
Yet lighter than the lightest bee.
You see it here, you see it there,
You see it ALMOST everywhere.
Like the chameleon, it changes colors,
Red, purple, blue and others.
It was there at dawning light,
It will be there at deep, dark night.


2) There is one in a minute and two in a moment,
but only one in a million years. What is it?


3) In a stable there are men and horses. In all,
there are 22 heads and 72 feet. How many men
and how many horses are in the stable?
