The magic cup

There is a cup in the garden
Within which the fairies hide
A giant cup with magic powers
Why don’t you come inside
It spins around so fast you see
Spinning through the air
It goes so quick you’ll feel the wind
Flowing through your hair
It could take you to another land
Or very foreign place
Or come out on another realm
Where there’s no time or space
But beware, some folk have heard
It’s function has since changed
A tree was planted into it
A flower pot remains
