What is quick? A sailfish swimming from fishmongers. And a beam of light travelling from the sun to Earth.

What is slow? A snail sitting on the ground. And a bottle bobbing across the sea.

What is smooth? A pebble worn smooth over time by the tide. And a glass sphere.

What is rough? A piece of leather. And remembering pi.

What is hard? A plank of wood. And a piece of metal.

What is soft? A petal of a blossoming flower. And a fluffy pillow.
