Answer:
I have wheels and flies yet I am not an aircraft.
I am gentle enough to soothe your skin light enough to fly in the sky and strong enough to crack rocks.
I contain five little items of an everyday sort. You can find all five in a tennis court.
I always run but never walk often murmur but never talk have a bed but never sleep has a mouth but never eat.
I have a neck but no head arms but no hands. What am I?
Before I grow I'm small. When I'm old I grow tall. When I die I give a mighty fall.
