Go and catch a falling star

Hi everyone :)

One day, while Sophie and Calcifer are talking, Michael is having trouble with the spell that Howl has given him to learn. He asks Sophie to help with his homework. Sophie takes a look at the spell.
It is the following:

    Go and catch a falling star,
       Get with child a mandrake root,
    Tell me where all past years are,
       Or who cleft the Devil’s foot,
    Teach me to hear mermaids singing,
       Or to keep off envy’s stinging,
           And find
           And wind
    Serves to advance an honest mind.
    (John Donne, Song)

    Decide what this is about, write a second verse yourself.

Sophie cannot make out what it is all about. Sophie and Michael discuss the spell for a long time. Finally they decide that they should do what the spell says, and do the first line “Go and catch a falling star.” Calcifer tells them he does not want them to go, but they leave. Sophie and Michael arrive at the marsh and wait for the falling star. Suddenly stars start to fall, Michael is going to catch a star. However, the star looks frightened of Michael and Sophie and does not want tem to catch. Thus, the star chooses to die rather than be caught, and falls into the marsh and disappears. Sophie and Michael go home sadly.
