Loopholes !

Hey Guys, There are so many loopholes in the story of Rapunzel. For instance ,

1. how did the witch put Rapunzel in the tower ?

2. If there was stairs or if she fly on a broomstick why she cant use cant use that instead of climbing the hair ?

3. After cutting Rapunzel's hair  how did she get down to leave Rapunzel in the forest and how she climbed up afterwards to wait for the prince ?

And I am stuck ! Really stuck ! Does anybody know where Brother Grimm lives ? We could ask him!
