Let's guessOnline version Read carefully the cluesssssss by Paola Bayona 1 You feel it, but never see it and never will. Hints 1 What has roots as nobody sees, Is taller than trees, Up, up it goes, And yet never grows? 2 As light as a feather, but you can't hold it for ten minutes. 3 Has a mouth but does not speak, has a bed but never sleeps. 4 Runs smoother than any rhyme, loves to fall but cannot climb!
