I am small as an ant and big as a whale,
I can soar through the air like a bird with a tail.
I can be seen by day and not by night,
I can be seen with a big flash of light.
I follow whoever controls me by the sun,
but I fade away when dark fell like a ton.
What am I?
The fishmonger is 1.8 meters tall. He wears size 8 shoe and wears XXL shirts. What does he weigh?
