Miss Tick
A Matter of Some Gravity is a 1996 Uncle Scrooge adventure comic written and drawn by Don Rosa, featuring sorceress Magica De Spell. Like some other comic stories by Rosa ("Cash Flow" and "The Universal Solvent"), the story is founded with toying with the laws of nature, specifically gravity. Rosa claims that he got the ideas for those comics during a mechanical engineering course in an institute of higher education, which he took before he became a professional cartoonist.
