User blog comment:General MGD 109/Is there any magic?/@comment-1966944-20120414083309/@comment-1509826-20120415084745

good points, and your possibly/probably right, although I still don't get if they physically change, only Grimms can see them.

As for my comment, I ment in the world of fiction, not in reality. I know there is no such thing as magic only science.

Any thanks for your point, I didn't truthfully think of the idea of them having human DNA, and I know vibrations interfear with the brains workings, I just didn't think they could be done on that level with an ordinary violin.
